Abstract: Active disturbance rejection control (ADRC) for a quarter-car active suspension system is proposed. The performance of ADRC is compared with benchmark (LQR control) from current literature. A simulation experiment is performed to investigate the performance of ADRC in comparison with passive system and the LQR control, as well as to test the ability of ADRC to cope with varying process. Results show that ADRC performs better than the benchmark control and is able to cope with varying process commonly seen in active suspension system.

Keywords: active suspension system; ride comfort; active disturbance rejection control; ADRC; LQR control; linear quadratic regulator; nonlinear springs; nonlinear dampers; actuator saturation; ride performance; simulation; vehicle suspension; vehicle vibration.
