On Discrete Time Output Feedback Sliding Mode Like Control for Non-minimum Phase Systems
نویسندگان
چکیده
This paper presents a novel approach to the problem of discrete time output feedback sliding mode control design, where the system to be controlled is non-minimum phase. The method described in this paper applies to uncertain (square) systems with matched uncertainties. A connection between previously established output feedback min-max controllers and discrete time sliding mode controllers will be given, which is crucial to the approach presented. A new explicit method will be described to solve a constrained Riccati inequality which allows the calculation of the ultimate boundedness sets associated with the controller. A numerical example from the literature is used to illustrate the results described in the paper.

A Current-Based Output Feedback Sliding Mode Control for Speed Sensorless Induction Machine Drive Using Adaptive Sliding Mode Flux Observer
This paper presents a new adaptive Sliding-Mode flux observer for speed sensorless and rotor flux control of three-phase induction motor (IM) drives. The motor drive is supplied by a three-level space vector modulation (SVM) inverter. Considering the three-phase IM Equations in a stator stationary two axis reference frame, using the partial feedback linearization control and Sliding-Mode (SM) c...
متن کاملDesign of a Novel Framework to Control Nonlinear Affine Systems Based on Fast Terminal Sliding-Mode Controller
In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. One of the main advantages of the proposed approach is that only the outputs and external state...
متن کاملAdaptive fuzzy pole placement for stabilization of non-linear systems
A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...

متن کاملIntegral Sliding Mode Output Tracking Controller for Sampled-Data Systems
A new integral type sliding surface (ISM) is design for sampled-data systems for output tracking. ISM surface design is based on Output Feedback. Discrete-time control based on ISM achieves good tracking performance while allowing the pole assignment of m poles, where m is positive integer, which are otherwise zero in a deadbeat design. It will be shown in this work that, the discrete-time vers...
