The paper solves the observer-based Hinfin control problems of T-S fuzzy systems. Two conditions that guarantee the existence of Hinfin controller based on fuzzy observers are developed. The conditions are more relaxed than the existing one and ensure the designed fuzzy controller achieving a better Hinfin control performance. A numerical example is given to demonstrate the validity and applicability...
This paper deals with the stabilization problem for discrete-time nonlinear systems that are represented by the Takagi - Sugeno fuzzy model. By the multiple fuzzy Lyapunov function and the three-index algebraic combination technique, a new stabilization condition is developed. The condition is expressed in the form of linear matrix inequalities (LMIs) and proved to be less conservative than existing...
The tracking control problem of T-S fuzzy systems is solved in the paper. A new method is proposed to improve the existing result. All the designed conditions are expressed in the form of LMIs. Thus they are numerically realizable. From the simulation example, it can be seen that the proposed approach achieves a better tracking performance.
By using the non-PDC control and the multiple Lyapunov function, a set of LMI-based stabilization conditions for continuous-time T-S fuzzy systems is developed in the paper. In comparison with existing results, not only the derived condition is more relaxed but the approach used is simpler and more realizable in dealing with the time derivatives of membership functions. Some drawback existing in current...
For the control of ship electric propulsion interior permanent-magnet synchronous motor (IPMSM), the position-sensorless observer and based neuro-fuzzy PI controller had been designed, the position sensorless of the flux-observer-based control scheme can obtain an accurate knowledge of the motor magnetic behavior, and lead to good robustness against load variations. A fuzzy basis neuro-network is...
