| Summary: | This paper aims to investigate the performance of linear quadractic
regulator (LQR), robust H∞ and passive controller for active suspension of the
quarter car model. The presented approach is based on linear model well
supported by computer-aided control systems design (CACSD) tool which
yields faster control design approach. The linear active suspension provides
better handling and ride comfort by suppressing the vibration induced due to
road disturbance. Road disturbance was added to check the vibration limitation
by these controllers. Results were evaluated in both the frequency domain and
the time domain. The results show the impact of active suspension techniques
on vehicle dynamics and passenger comfort and handling. |
