Abstract

This paper present the Composite Nonlinear Feedback Control and Proportional Integral Sliding Mode Control (CNF-PISMC). The advantages of Composite Nonlinear Feedback Control are reducing overshoot; improve transient performance and fast response. The advantages of PISMC are to overcome uncertainties and steady state error in the system. The used of a boundary layer solution in the control law of CNF-PISMC is to reduce the chattering problem. The result of the boundary layer thickness is representing the ability of the CNF-PISMC controller in MacPherson strut active suspension system. The value of boundary thickness is tuned by using Evolutionary Strategy (ES) to provide the two values of boundary layer thickness. The multi-body dynamics system software so called CarSim is used for validation purposes.
