The conventional reset control is simple for implementation by resetting some of its controller states to zero when its input is zero. However, we find that in some cases the performance of conventional reset control is still limited such as only partial reduction of the overshoot. Thus, this paper presents the stability analysis and design of an improved reset control system, where the reset times are prespecified and the controller states are reset to certain non-zero values, which are calculated online in terms of the system states for optimal performance. Experimental results on a PZT microactuator positioning stage show that the improved reset control can completely remove the overshoot and thus achieve shorter settling time than the conventional reset control. Moreover, robustness tests against various step levels, disturbance and sensor noise are presented.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116708595","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 neural network scheme herein is called adaptive backstepping neural controller (ABNC). In this study we have combined ABNC along with the classical controller to enhance the failure tolerance of the latter using the feedback error-learning paradigm due to Gomi and Kawato. The ABNC controller uses radial basis function neural networks with on-line learning without prior training. Information about actuator failures is not available to the controller for use in reconfiguration. The baseline controller required for the feedback error learning has been designed using a classical design approach to achieve the desired autonomous landing profile with tight touchdown dispersions called therein as the pillbox. The baseline design is capable of meeting touchdown requirements in severe winds but is not specifically designed for failures. The performance of the classical design augmented with the ABNC based neural controller is studied in detail for predefined failure scenarios. The failures considered in this study are: i. Single faults of either aileron or elevator stuck at certain deflections and ii. Combination fault for both one aileron and one elevator stuck at different deflections. A hard over failure of particular interest in this study is that of both the ailerons being stuck at particular deflections. Simulation studies indicate that the neural controller aids the baseline controller, significantly enhancing the fault-tolerance envelope.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131804274","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 MF stabilizer is based on model-following servo control (MFSC). The MFSC guarantees the error converges to 0 and the stabilization of the closed-loop system. The proposed method provides not only the servo capability to the actuated link but also the stabilization of the unactuated link. For the proposed MF stabilizer, the stable reference model chosen is the Furuta pendulum under the artificial gravity field, where the gravity is directed upward. The reference model chosen has stable equilibrium points at upright position. This paper gives the simulation results of the Furuta pendulum controlled by the MF stabilizer. The validity of the proposed design method is studied through the simulation of swing-up/stabilization control.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133718188","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}

Different normal form techniques, approximation methods, and perturbation procedures have been used to analyze these systems. In recent years, a novel approach, called modal series method, has been introduced and used to study the behavior of autonomous nonlinear dynamic systems of the form x = g(x). In this paper, we extend this approach to a wide class of nonautonomous nonlinear systems of the form x = g(x,i). Using two textbook examples, we show the capability of this extension to find approximate solutions for nonautonomous nonlinear systems.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133194302","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}

Since the pickup head is very close to the optical disk, air bearing disturbance has significant effect on flying height control. The effect is not constant and dependent on various parameters. The previous method can not effectively cancel air bearing disturbance. By contrast, this study improves the adaptive inverse control method to overcome this problem.

The airship is a nonholonomic system described by a set of nonlinear equations and the dynamics are subjected to bounded uncertainties. A smooth and time-varying coordinate transformation is proposed to reduce the disturbance rejection problem of the airship to that of a simple linear time-invariant system. A new robust feedback controller provides global stabilization and asymptotical rejection against the wind disturbance under the plant uncertainties. The proposed design method is simple and straightforward. Experiments are performed to validate the effectiveness of the proposed controller.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125847328","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}
