TL;DR: Transient performance of the yaw rate has improved with the increased speed of in tracking and searching of the best optimized parameter estimation for the linear and the nonlinear gain of CNF controller.

TL;DR: It is expected that the propose high performance robust control strategy could improve the yaw rate transient performances in presence of uncertainty.

TL;DR: The Composite Nonlinear Feedback (CNF) controller is proposed as a control strategy to reduce the high overshoot on the transient response and fast settling time in the MacPherson quarter car suspension.

TL;DR: The control algorithm called the Conventional Composite Nonlinear Feedback (CCNF) control was introduced to achieve the best transient response that can reduce to overshoot on the sprung mass and angular of control arm of MacPherson active suspension system.

Abstract: Yaw stability control is the most popular topics in automotive field. Several of studies have been done in searching the effective method in controlling yaw moment so that the vehicle will be in safe condition in certain cornering maneuvers. The main controller to control this is by using Composite nonlinear Feedback (CNF) which is very good in producing an output signal with a quick response and an overshoot at permissible level. The steering angle will be generated by the controller based on the feedback of yaw rate and side slip angle as an input. Simulation result has proved that the yaw rate and side slip angle are overall improved tested with different road profile and condition.
