There are 2 kinds of torque present when considering saturation. They are static and vibrating torque. The frequency of vibrating torque is double the motor speed. While there is only one current mode in the sinusoidal wave, there are 3 modes in the inverter drive. The domains are clearly displayed in the characteristics in terms of modified factors.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115673980","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}

Online planning has an advantage over the traditional off-line planning in reducing the influence of such factors as disturbance. In the the proposed method, the online planner is designed as a part of the control system by traditional design methods for control systems. Preview planning is added to the online planning in order to utilize the future restriction of the desired signal. Online planning constructs a feedback loop and preview planning adds feedforward to it. By integration of preview planning and online planning, the planner can prevent the controlled variable from spilling over the permitted domain better than without preview planning. This method is applied to a 3-wheeled vehicle, so that the vehicle can start to avoid obstacles earlier than the case without preview planning.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129809707","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}

In the NBAC, a neural network (NN) is connected in parallel with a linearized plant model, so that the NN is expected to identify the uncertainties included in the plant. At the same time the NN works as an adaptive controller that can compensate for the unknown system dynamics. At first, stability of the NBAC system including the nonlinear NN is analysed and a sufficient condition of the local asymptotical stability is derived by the Lyapunov stability technique. Then, the NBAC is applied to the torque control of a flexible beam that includes linear and nonlinear uncertainties caused by a contact force and by not exactly known shape and material of the beam. Experimental results illustrate effectiveness and applicability of the NBAC.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130074061","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}

In this paper, we propose an improved design scheme of the adaptive pole-placement control for the pneumatic servo system with additive external forces. In this design scheme, difference process of the signals in the identification mechanism and the compensator in the controller are introduced to eliminate the influence of the constant disturbances caused by the additive external forces. Furthermore, a multirate type adaptive law is adopted to improve the control performance. The effectiveness of the proposed design scheme is confirmed by experiments using the existent pneumatic servo system.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129051830","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 controller is constructed having two independent feedforward and feedback controllers. The feedforward controller has been designed considering the inverse dynamics of the flexible arm system. Since the flexible arm system has non-minimum phase characteristics, the inverse dynamics has been divided into causal (stable) and anticausal (unstable) parts and has been solved in time domain to obtain the feedforward control input. In order to provide stability robustness against unmodeled dynamics and performance robustness against frictions forces on the bearings, the feedback controller has been designed on the framework of H/sub /spl infin// control theory. The dynamics model of the flexible arm system has been formulated using a distributed parameter system method and the validity of the model has been experimentally verified.

The proposed controller is used to optimize a nonlinear objective function with different effective equality constraints. Minimum power losses and consequently maximum generated power can be obtained by controlling the inverter firing angle. The constraints are selected according to the optimal restrictions in order to ensure the duplication of the generated power when the speed varies from synchronous to double of the synchronous speed. The desired cost function in the nonlinear form is realized corresponding to the selected equality constraints when all the system optimal and stable requirements are taken into consideration. The optimal regulator theory is used and the Hassian matrix technique is selected in this study to facilitate the calculation of the optimal operation conditions.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134067591","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}
