Coordination Control Based on μ-synthesize for Electro-mechanical Transmission

The dynamic response of electro-mechanical transmission means to transfer the states form a steady phase to another one. There might be a big difference between the actual states and the expected during the transient process for the different dynamic response of the engine and the motors'. In order to improve the coordination capability, the theory of control based on model should be used. A system mode set is built based on the mode identification and normalization processed into a standard form. An augmented system is structured to integrate the optimization objective and the constraints into robust form, which is solved by the method of μ-synthesize. The validity of the coordinated is verified by the whole system's simulation based on vehicle driving cycle.
