The high computational complexity is explained by the allowance of concurrent motions of all the agents. This results in a significant growth of the branching factor (up to 300) because all the combinations of simultaneous motions are legal. Another difficulty is that when making a move, each side is uncertain about the concurrent motions of the other side. The linguistic geometry tools generated a solution of the problem demonstrating a dramatic search reduction for this totally concurrent system.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134082882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The largest block of this research consists of twenty-one projects that make up the \"Intelligent Control Systems Initiative\", jointly funded by EPRI and the National Science Foundation. Most of these projects began in 1993 and will continue for three years. The rest of EPRI's exploratory research projects, that address intelligent and adaptive control in general, are part of the program in applied mathematics and information science (AM&IS). This area emphasizes fundamental theory and design procedures. However, the AM&IS program also includes projects that seek to invent and test new techniques and new applications whose success appears relatively risky at the beginning of the project.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122527032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leader records the range-to-obstruction to either or both sides as well as its own estimated position and orientation. A non-model-based technique is used to correlate the follower's estimate of position to the leader's. The technique is tolerant of changes in the environment between passes of the leader and follower, and eliminates the correspondence problem in a model-based system where both the leader and follower need to correctly identify a particular object as being the same landmark.

The objective is to produce tasks with the greatest level of performance and the least amount of cost. Task performance is evaluated through the development of reliability estimates that measure the individual types of uncertainties present in the task. These reliability estimates, in conjunction with cost measures, are incorporated into the mathematical framework developed in RBC. Within this framework, the optimal information selected for each task ensures that the task will be executed with maximum reliability and minimum cost. A case study involving robotic assembly is presented in order to illustrate these results.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126404297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A conventional proportional-integral-derivative (PID) guidance scheme is first employed to form the basis for the fuzzy terminal guidance. The PID guidance scheme employs heading and flight path angle errors derived from sensor imagery of target location to compute angular rate commands. The fuzzy logic terminal guidance design procedure involves translating the conventional PID guidance scheme into a fuzzy control structure with the associated fuzzification of input/output variables, encoding of decision-making knowledge into rulebases, and defuzzification. A novel scheme is implemented in which fuzzy rulebases are used to generate and combine PD and PI portions of the guidance commands. Additionally, the fuzzy terminal guidance includes rulebases to control speed and to perform gain scheduling. Performance evaluations demonstrate the feasibility of the approach.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"100 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133720932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a workcell should possess the ability to automatically probe, reconstruct the surface geometry, determine the tool path for further machining, and finally carry out edge finishing. The robot chosen is YAMAHA Zeta-1 robot designed specifically for deburring. Probing is accomplished by means of a displacement sensor. This obviates the need for an additional probing stage in the process. The workcell controller has an information processing part consisting of a PC-parallel processor network, an interface to communicate with the controller of the deburring robot and a hardware interface for the probe. The surface of the workpiece is probed by the robot, directed along a path prescribed by the PC-parallel processor network, based on the original CAD database. The probed points, thus collected are used to reconstruct the surface probed and extrapolate to obtain the edge profile. The tool path constructed from the edge profile is then used to direct the robot during machining. Results of edge tracking of a saddle surface in three dimensions is presented. The geometric tacking error is found to be within the resolution of the command signals (0.063 mm).","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132359196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, the extra degrees of freedom have been used to optimize a single criterion such as joint torques minimization, obstacle avoidance, or minimization of flexible base vibrations. Because these approaches do not consider hardware limitations such as joint and rate limits, optimizing a single criterion often leads to high joint velocities and instabilities. To overcome these problems, it has been suggested that multiple criteria be optimized. Although optimizing multiple criteria offers the possibility of stabilizing joint solutions, it is difficult to choose the required weights associated with each criterion. This paper presents results using a fuzzy logic supervisor to decide the relative importance of each criterion and compute time-varying weights.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132191947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
