Efficiency Optimization Control Strategy of Scroll Expander Generator System
摘要
Abstract
The minimum air consumption as the efficiency optimization target for scroll expander generator system is first proposed and the optimization method combining the loss model method with the online search method is adoptd in this paper, which is profitable to avoid the adverse effect caused by the randomness of initialization and the change of conditions. In view of the nonlinearity characteristic of the power generation system due to nonlinearity the pneumatic system and randomness of load, the control strategy combining compensation control based on supply pressure feedback linearization and speed PI tracking control is used. It is effective to compensate for nonlinearity of supply pressure and tracking without steady-state error of optimal speed. The experimental results indicate that the optimal control strategy is effective for speed optimization and tracking, and the goal of minimum air consumption can be achievd.关键词
