The Dynamic Model and Control Algorithm for the Active Suspension System

Road surface roughness is the leading cause of vehicle oscillation. The suspension system used to dampen these oscillations. active equipped with a hydraulic actuator more efficient than passive one. Therefore, it replace system. article reviews and analyses models control algorithms for systems. In this article, author mentioned three dynamic commonly simulate oscillations: quarter-dynamic model, half-dynamic fully model. Each can be considered state variable in Besides, algorithm significant. Algorithms like PID (proportional–integral–derivative) LQR (linear quadratic regulator) will fit linear contrast, nonlinear model’s algorithms, such as SMC (sliding mode control), fuzzy, ANN (artificial neural network), perform better. Overall, oscillation significantly improved once an used. contents analysed database selecting by other researchers future.
