Design of Sliding Mode Control for Nonlinear Uncertain System

Instrumentation and Control Engineering

This paper extends a recent result on sliding mode control with mismatched uncertainties. Sliding Mode Control has been recognized as one of the key approaches for the systematic design of robust controllers. Mostly it is found for controlling of complex nonlinear dynamic systems operating under uncertainty conditions. Sliding mode control is a nonlinear control technique have properties of accuracy, robustness, and easy tuning and implementation.The major advantage of sliding mode controllers is inherent insensitivity to parameter variations and disturbances in the system, thereby eliminating the necessity of exact modeling of the system. The practical stability of the overall system is proved and the results are verified by simulation of an illustrative example.
