A Chattering Suppression of Proportional Sliding Mode Control with Composite Nonlinear Feedback Technique using Sigmoid Function for MacPherson Active Suspension System

A Chattering Suppression of Proportional Sliding Mode Control with Composite Nonlinear Feedback Technique using Sigmoid Function for MacPherson Active Suspension System

The chattering problem phenomenon occurred due to the high-frequency switching of a sliding mode controller exciting unmodelled dynamics in the closed loop. Unmodelled dynamics may be those of sensors and actuators neglected in the principal modelling process since they are generally significantly f...
