Ride comfort performance of a non-linear full-car using active suspension system with active disturbance rejection control and input decoupling transformation
In this paper, active disturbance rejection control (ADRC) and a
control method combining ADRC with input decoupling transformation
(ADRC-IDT) are proposed to improve ride comfort of a non-linear full-car
with active suspension system. Simulation of the model in frequency domain as
well as time domain with three types of road profile – speed hump, double
bumps and random excitation, as the disturbance to the system is performed to
evaluate the performance of the proposed ADRC-IDT in comparison with
ADRC and the passive system. Through experimental simulation studies, the
ability of the proposed controllers to cope with varying process is investigated.
Results show that ADRC-IDT was able to produce comparable performance to
a typical ADRC control structure with less number of control parameters
