The Development of Air Suspension Controller in Mechanical Engineering Based on DSP

Cylindrical air spring suspension’s vehicle model with seven freedom degrees is established. Then the model is simulated by use of Matlab/Simulink to accomplish the simulated-computation of the driving state such as rolling angle and pitching angle. Based on the above work, air suspension controller, DSP TMS320F2812 chip as the core processor, is developed. The result of the real vehicle test proves that the controller can obviously improve vehicle’s driving smoothness and handling stability, so it meets the applying requirements.
