Cooperative Control of Interconnected Air Suspension Based on Energy Consumption Optimization

In this study, a cooperative control method based on model predictive and multiagent theory is proposed to an interconnected air suspension system with three controllable structures of interconnection mode, damping, vehicle height. The controller constructed discrete-time state-space model. optimal interval for force obtained through solving cost functions while satisfying set constraints controlled variables thereby reducing the coupling complexity multivariable system. Deliberative agents are involved in building height adjustment, damping force, energy consumption strategy established realize distribution low consumption. Finally, test results show that can significantly improve ride comfort restrain rollover premise ensuring efficiency. Compared traditional control, peak value sprung mass acceleration speed decreases by 70% unsprung 75% under straight-driving condition. roll angle 40% steering As they skyhook, imitation PID-PWM strategies.
