Abstract

A brand new controller with different mixture of Sliding Mode Control and Fuzzy Logic is suggested. The traditional sliding surface is modified using some fuzzy rules. This mixture confers controller sturdiness and versatility. A neutralization process along with a mixing process are utilized to compare the performance from the new controller to what conventional sliding mode controller along with a PID controller.

Keywords

• Fuzzy surface
• Sliding mode control
• Chemical processes
• Nonlinear process
