In this paper, new non-quadratic stability conditions are derived based on the parallel distributed compensation scheme to stabilize Takagi-Sugeno (T-S) fuzzy systems. We use a non-quadratic Lyapunov function as a fuzzy mixture of multiple quadratic Lyapunov functions. The quadratic Lyapunov functions share the same membership functions with the T-S fuzzy(More)
This paper develops a new direct model reference fuzzy adaptive control of SISO continuous-time nonlinear systems. The model following conditions are assured by using an adaptive Takagi-Sugeno (TS) fuzzy system as nonlinear state feedback controller. Both full state information and observer-based control schemes are investigated. It is shown, that the(More)
In this paper, a new non-quadratic stabilization approach is used to stabilize a two-link robot manipulator. We use a non-quadratic Lyapunov function as a fuzzy blending of multiple quadratic Lyapunov functions. The quadratic Lyapunov functions share the same membership functions with the T-S fuzzy model. The proposed approach is based on two assumptions.(More)
An adaptive neural network backstepping control for a class of uncertain nonlinear systems is presented in this paper. Three main issues will be treated: (1) unknown nonlinearities; (2) unknown system parameters; (3) external or internal disturbances. The proposed technique is applied to a simple pendulum. This latter is an unstable system which is(More)
The direct torque control(DTC) is one of the actively researched control which is based on decoupled control of flux and torque. Among all methods of torque control of permanent magnet synchronous motor (PMSM), DTC achieves robust and fast torque response without the need of speed or position sensors, coordinate transformation, PWM pulse generation and(More)
