Matching with the abilities of the actors and the sensors, a mixed-sinusoid-based maneuvering path is proposed. Not only the advantage of sinusoid maneuver path over appendices vibration excitation is kept, but the time optimality of the step curve is taken into consideration, through which the maneuver speediness and the excited vibration smoothness are conciliated. The designed path in some sense optimizes the maneuver time, which is especially suitable for large-angle and agile-maneuver path programming of spacecraft with relatively rigid appendices. Numerical simulation illustrates that mixed-sinusoid-based maneuver path reaches time approximate optimality and performance approximate optimality simultaneously.","PeriodicalId":426967,"journal":{"name":"International Conference on Informatics and Analytics","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121503851","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 new control law accounts for adverse effect caused by the gyroscopic effect of propellers that the increased speed leads to high order of oscillation. The proposed controller rapidly converges when reaching the equilibrium point, dramatically improving the convergence speed compared to the classical PID control law.

But the PID controllers without well-tuned parameters will seriously affect, resulting in a large waste of resources as well as lack of efficiency and safety of production. Instead of manual tuning, modern complex industrial process demands a common computing program to get the tuning task done, so the self-tuning PID technology make a huge progress. Still the limitation of correspondence is hard to overcome. In this paper, a design of PID auto-tuning procedure based on LabView is introduced to solve this problem, which is compatible of the majority of communication with VISA interface. Selecting fuzzy tuning as the self-tuning method, it carries out real-time PID controller parameter tuning according to fuzzy rules. This article firstly accomplishes the design and simulation of process control with LabView toolkit, and then the practical temperature control of Zirconia Oxygen analyzer. The outcome verifies the capability and operability of the design.","PeriodicalId":426967,"journal":{"name":"International Conference on Informatics and Analytics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127799440","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}

This control strategy consists of two parts: firstly, a time-varying sliding mode controller is designed to make the tracking errors to zero at a desired finite time t r ; then, in the succeeding time t > t r , another nonsingular terminal sliding mode controller is used to make the tracking errors stay at zero. The algorithm has the following advantages: 1) the tracking error convergence time can be set in advance; 2) error convergence rate can be adjusted by changing the value of a parameter; 3) global robustness is guaranteed for parameter uncertainty and external disturbance. Numerical results demonstrate the usefulness of the proposed control strategy.","PeriodicalId":426967,"journal":{"name":"International Conference on Informatics and Analytics","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125888324","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}
