چکیده
This brief proposes an invariant manifold based output-feedback sliding mode control (SMC) strategy for systems with mismatched disturbances to achieve asymptotic tracking and disturbance rejection. Different from the existing SMC methods, is employed transform multiple into matched ones, which can provide full system dynamics controller design improve accuracy. An observer developed estimate unmeasurable states, then proposed. Moreover, switching gain of adaptively changes estimation error, reduces chattering in SMC. Experiments on a converter-driven DC motor verify superiority proposed method.

Static output feedback sliding mode control for time-varying delay systems with time-delayed nonlinear disturbances
In this paper, a robust stabilization problem for a class of linear time-varying delay systems with disturbances is studied using sliding mode techniques. Both matched and mismatched disturbances, involving time-varying delay, are considered. The disturbances are nonlinear and have nonlinear bounds. A sliding surface is designed and the stability of the corresponding sliding motion is analysed ...
متن کاملOutput Feedback Sliding Mode Control for Mimo Discrete Time Systems
In this paper we present a new algorithm for discrete sliding mode control of linear multivariable systems using fast output sampling feedback. Here we make use of a single switching surface regardless of the number of inputs. The main contribution of this work is that instead of using the system states, the output samples are used for designing the controller. Numerical example demonstrates th...
متن کاملDiscrete time Output Feedback Sliding Mode Control for Uncertain Systems
This paper describes a method for designing discrete time static output feedback sliding mode controllers. Previous work has shown that by identifying a minimal set of current and past outputs, an augmented system can be obtained which permits the design of a sliding surface based upon output information only, if the invariant zeros of this augmented system are stable. In this work, a procedure...
