A scroll expander exhaust recovery system with the battery storage was proposed to improve exhaust re-covery efficiency. Considering exhaust flow,storage pressure and battery current,expander supply pressure was optimized by use of the loss model based on the over/deficient expansion and generator copper loss. With the input-output linearization method,supply pressure PI controller was designed to track the supply pressure reference. DC bus voltage was efficiently regulated by the PI voltage controller,the duty feedforward compensation and the opera-tion mode of battery storage system. Experimental results proved the validity of the control strategy,realizing the maximization of exhaust recovery with regard to the efficient operation of load power and exhaust discharging system.
