Differential Evolution-Based PID Control of Nonlinear Full-Car Electrohydraulic Suspensions

Differential Evolution-Based PID Control of Nonlinear Full-Car Electrohydraulic Suspensions

This paper presents a differential-evolution- (DE-) optimized, independent multiloop proportional-integral-derivative (PID) controller design for full-car nonlinear, electrohydraulic suspension systems. The multiloop PID control stabilises the actuator via force feedback and also improves the system...
