If the need of customer can not be satisfied, another time window is assigned to the customer. Firstly, the initial routings are constructed by some strategy in which the rearrangement of time window is considered, and then a tabu search algorithm is employed to improve the initial routings to minimize the total traveling cost.

A new control scheme is proposed based on neural network technology and linear feedback approach for tracking a planned trajectory. The control system is established with two parallel subsystems designed separately. One is a linear controller based on state feedback with respect to a manifold that prescribed the desirable trajectory tracking performance, and another one is a learning controller designed with two neural networks. The former ensures trajectory tracking error regulation, the later is for force/torque generation required by the designed dynamic trajectory. A leaning law for online weight updating of the neural networks is derived such that the trajectory tracking accuracy is improved while the system remains in stable. Stability is analyzed using Lyapunov stability theory. Dynamic trajectory tracking control simulations are carried out on an industrial robot AdeptOne arm. The results demonstrate the effectiveness and usefulness of the proposed control scheme.","PeriodicalId":377192,"journal":{"name":"2008 7th World Congress on Intelligent Control and Automation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115320824","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 model of FOMC takes use of the lumped mass method in which FOMC is considered to be a system of micro units connected by elastic non-mass spring. Four order Runge-Kutta method is used to work out the equation of FOMC and ROV kinematics and dynamics. Simulation includes tension distribution and shape of FOMC and the motion of ROV under the condition of disturbance of FOMC. The simulation result indicates that the FOMCpsilas influence to ROV can not be neglected while we discuss the control problem of ROV.","PeriodicalId":377192,"journal":{"name":"2008 7th World Congress on Intelligent Control and Automation","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115373257","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}

But the pressure control system of cubic press in common use has the disadvantages of large zero drift, poor repeatability, and low control precision. To handle these problems, a novel pressure control system of cubic press has been developed. In this system, a cost-effective microprocessor ARM7TDMI (S3C44B0X) was employed, and an appropriate temperature compensation circuit was designed to reduce the negative influence of large environment temperature variation. The pressure boosting speed and pressure control precision were improved by three motors coordinated control. An efficient method was adopted to overcome the problems of large zero drift and poor repeatability by software. Furthermore, several measures were utilized to prevent the malfunction of system. Application results indicate that this control system has the advantages of low zero drift, high precision, good repeatability and reliability.","PeriodicalId":377192,"journal":{"name":"2008 7th World Congress on Intelligent Control and Automation","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115468069","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}

Although there are plentiful results about complex peg-in-hole assembly problems, little work has been done with respect to this special issue. In many cases, mating connectors can be regarded as a hole search process of a multiple hole-in-peg problem. Because various faults might occur during the search, a reliable error recovery strategy is necessary in the mating task. In this paper, we model possible faults as ldquotrap regionsrdquo in the configure space (C-space) of the assembly. Fault isolation methods are obtained from elaborated force analyses as well. Based on these fault isolation results, error recovery strategies are proposed according to the fault models. A fault-tolerant mating of electric connectors can then be achieved. The effectiveness of the methods is finally confirmed by experiments.","PeriodicalId":377192,"journal":{"name":"2008 7th World Congress on Intelligent Control and Automation","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123059125","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}
