This paper presents the stability analysis of a Variable Structure Adaptive Backstepping Controller (VS-ABC) for linear plants with relative degree one. Robustness properties with respect to parametric uncertainties and external disturbances are demonstrated, as well as, the system convergence in finite time. Moreover, simulation results are included for an unstable second order plant in order to...
Sliding Mode Controller (SMC) can achieve good tracking performance and robustness to the disturbances, but SMC has worse stability and reliability than PID controller. As a most widely used controller, PID controller has many obvious advantages, but it has poorer tracking performance than SMC. In this paper, a hybrid control method of sliding mode and PID controllers is proposed to fully combine...
The paper introduces the control method of the fuzzy sliding-mode control (FSMC) for electro-pneumatic proportional position system, designs the discrete FSMC system and its controller. The sliding surface and its switch function are designed by using the pole assignment method. The control law of the sliding mode is based on the exponential trending law. The switch function s(k) and its error ds(k)...
This paper proposes a realization of robust speed control for permanent magnet synchronous motor by using PD-Sliding mode hybrid control. The PD control has a good performance in the transient period while the sliding mode control has robustness against the system uncertainties. The proposed control method is proposed for the control of permanent magnet synchronous motor by taking advantages of both...
The problems of stochastic stability and sliding mode L2-Linfin control for a class of nonlinear matched and mismatched uncertain systems with stochastic jumps are considered in this paper. The uncertain system under consideration may have mismatched norm bounded uncertainties in the state matrix. The transition of the jumping parameters in the systems is governed by a finite-state markov process...
