Sliding Mode Control for DC Generator with Uncertain Load

Abstract

The paper deals with the design of a sliding mode controller for the DC power generator with a variable load. We show that the high quality control processes will be in the closed-loop system if the designed controller compensates the inner feedbacks for the control object and forms the desired motion path in the state space for the designed closed-loop system. The above-mentioned controller is designed by using interval methods, which allow simplifying model with uncertain dynamic. We design the controller and test the designed control system by using Chua's chaotic system as a source of uncertainty. The use of interval calculus, while the controller is being designed, defines the controller structure as second-order sliding mode controller. This control approach allows constructing a high-quality asymptotically stable multi-channel control system with a control error of less than 1%. The proposed in the paper approach allows designing different control systems for linear and nonlinear objects with uncertainty.
