This paper presents a comparison between adaptive input-output linearization and adaptive fuzzy sliding mode control (FSMC) for induction motor. At first, we describe the adaptive linearization control method, which consists in the cancelling of the nonlinearities and decoupling between speed and flux of the system when Rr and TL are unknowns constants. The adaptive sliding mode control, which is...
This paper is concerned with the problem of robust discrete-time sliding-mode control for a class of uncertain descriptor systems with time-varying delay and external disturbance. A new sliding function is proposed and sufficient conditions are derived to guarantee that the sliding mode dynamics is robustly admissible. Moreover, a quasi-sliding mode controller is established to satisfy the reaching...
This paper investigates the problem of sliding mode control (SMC) for a class of uncertain Takagi-Sugeno (TS) fuzzy descriptor systems with time-varying delay. An integral-type sliding function is proposed and a new delay-dependent stability criterion, in terms of linear matrix inequality(LMI), is derived which guarantees to the sliding mode dynamics to be regular, impulse free and stable for all...
This paper focuses on the synthesis of adaptive fuzzy fault tolerant controller which combines a sliding mode controller and a Proportional Integral controller (PI). The free parameters of the adaptive fuzzy controller as well as the PI controller are tuned on-line based on Lyapunov approach. The overall adaptive fuzzy sliding mode scheme guarantees the global stability of the resulting closed-loop...
