Design and simulation of sliding mode fuzzy controller for nonlinear system

الملخص EN

Sliding Mode Controller (SMC) is a simple method and powerful technique to design a robust controller for nonlinear systems.

It is an effective tool with acceptable performance.

The major drawback is a classical Sliding Mode controller suffers from the chattering phenomenon which causes undesirable zigzag motion along the sliding surface.

To overcome the snag of this classical approach, many methods were proposed and implemented.

In this work, a Fuzzy controller was added to classical Sliding Mode controller in order to reduce the impact chattering problem.

The new structure is called Sliding Mode Fuzzy controller (SMFC) which will also improve the properties and performance of the classical Sliding Mode controller.

A single inverted pendulum has been utilized for testing the design of the proposed controller.

Programming and Simulink by Matlab have been used for the simulation results.
