One of the main considerations in stability analysis is the low-frequency oscillations of rotor due to disturbances of which the power system is susceptible to. These oscillations may sustain and grow in magnitude to cause system separation if adequate damping is not provided, especially during using an AVR in the system. To enhance system damping, the generating unit is equipped with a power system stabilizer (PSS). Conventional PSS controllers are widely utilized in industry to damp the low-frequency inertial oscillations experienced due to disturbances. The design of such stabilizer encompasses finding the best settings of PSS parameters which yield the attainable damping response. Several design approaches and techniques have been proposed (i.e. sequential PSS design, Ha>; optimization technique, etc.) over the years. A novel genetic-algorithm (GA) based optimization approach to design a robust PSS is presented in this paper. This proposed approach employs optimization of damping factor (σ) and damping ratio () in parallel with speed deviation based performance index (IAE) optimization, to obtain the best possible time-domain results (minimum settling time, sserror, etc.). The well-known single-machine infinite bus system is used here. Simulation of the linearized system is presented. The system speed response is investigated with and without PSS. Their results are compared and show that the response of the system with PSS sustains its stability during system upsets, which means that the proposed method gives encouraging results compared with traditional methods.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120961333","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 structure of the controller consists of two models that describe the kinematics and dynamics of the mobile robot system and a feedforward neural controller. The models are modified Elman neural network and feedforward multi-layer perceptron respectively. The trained Elman neural model acts as the position and orientation identifier. The feedforward neural controller is trained off-line and adaptive weights are adapted on-line to find the reference torques, which controls the steady-state outputs of the mobile robot system. The feedback neural controller is based on the posture neural identifier and quadratic performance index optimisation algorithm to find the optimal torque action in the transient state for N-step-ahead prediction. General back propagation algorithm is used to learn the feedforward neural controller and the posture neural identifier. Simulation results show the effectiveness of the proposed adaptive neural predictive control algorithm; this is demonstrated by the minimised tracking error and the smoothness of the torque control signal obtained with bounded external disturbances.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125261386","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}
