Output Feedback Integral Sliding Mode Control for Uncertain Systems with Bounded L2 Performance

Discrete 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...

Fast Output Sampling Based Output Feedback Sliding Mode Control Law for Uncertain Systems

A method for achieving sliding mode in uncertain systems is presented in this paper. The algorithm uses a fast output sampling control strategy that would avoid the use of switching in the control input and hence avoids chattering. This method does not need the measurement of the system states for feedback as it makes use of only the output samples for designing the controller. Thus, this metho...

Output Feedback Sliding Mode Control for a Class of Uncertain Multivariable Systems with Unmatched Nonlinear Disturbances

LMI based bounded output feedback control for uncertain systems

The paper provides conditions for constrained dynamic output feedback controller to be cost guaranteeing and assuring asymptotic stability for both continuous and discrete-time systems with quadratically constrained nonlinear/uncertain elements. The conditions are formulated in the form of matrix inequalities, which can be rendered to be linear fixing one of the scalar parameters. An abstract m...

Output 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...
