Fuzzy Logic PID Control Hybrid Electronic Vehicle Based on Dynamic Processes

Control for the HEV propulsion system based on dynamic processes is proposed.Parameters of the controller are optimized in order to optimize the dynamic characteristics.For the purpose of solving the problem that the energy consumption will increase while the dynamic characteristics are optimized,fuzzy-PI-control is put forward for the HEV.The dynamic characteristic is than improved,and the output required from the engine and motor will not go beyond their ability,which allows the optimized target of the control strategy to be implemented.
