Design For Controller Of The Novel Double Rotor Motor Applied To The Hybrid Electric Vehicle System

With the decrease of global petroleum resources and the severity of world-wide air pollution, development for new technology of Hybrid Electric Vehicle (HEV) is becoming the focus in this field. Hybrid Electric Vehicle (HEV) is an automobile that is provided with the electric power drive system and the Assistant Power Unit (APU) in the meantime. Hybrid Electric Vehicle (HEV) has some advantages such as high economy of fuel, high performance and low exhaust compared with Electric Vehicle (EV) and traditional automobile.If the technology of Hybrid Electric Vehicle (HEV) will be developed in the future, it needs to be resolved the problem that is coupling transmission mode of electromechanical system. So, it is an important thing of development the technique of Hybrid Electric Vehicle (HEV) that a kind of high performance motor drive system is developed and an effective control method of it is adopted.A kind of novel motor configuration of Double Rotor Motor applied to the Hybrid Electric Vehicle (HEV) system is proposed, and the controller of it is designed in this paper. It has some advantages such as simple configuration, reasonable power allotment ratio, working credibly and so on. It resolves the problems that are the structure is complicated and power is imbalanced of two motors connection configuration in traditional Hybrid Electric Vehicle (HEV) in theory.The controller of this Double Rotor Motor is designed in this paper. First of all, mathematical model of the Double Rotor Motor is derived, and the control method of rotor magnetic field oriented is proposed. Then the validity of them is verified by Mat Lab/Simu Link/S-Function numerical simulation. Next, the hardware circuit and the software control system of the controller are designed in this paper. It consists of power circuit, control and sampling circuit, switch power supply circuit, and the display circuit in structure. In control system, it takes the DSP of TMS320LF2407 as control core. It is proposed a kind of control method of rotor magnetic field oriented to achieve the working states of this motor by simulating. Therefore, it is verified that the Double Rotor Motor applied to Hybrid Electric Vehicle (HEV) system is feasible.
