Abstract: The paper presents a review of the sensorless position estimation algorithms which are being adopted by Automobile Air-condition. After analyzing and introducing of the sliding mode variable structure theory and the mathematic model of PMSM, the control strategy based on SMO and its math expression are presented. The simulation model in MATLAB/SIMULINK is established, in which the real rotor position and the estimated rotor position calculated by SMO under dynamic and static state are analyzed. Besides, the principle of sliding gain selection is raised. The simulation provides the theoretical foundation.

Abstract: In order to improve the reliability and comfortableness of driving, network used in automobile air-condition control system have been studied in this paper and we also designed a automobile air-condition control system based on CAN bus. The control system can improve the reliability of driving, it interconnects the air-condition system with other automobile CAN buses, which accelerating the automobile integration process. To optimize the control of vehicle air-condition system, we can improve and enhance the performance of conventional automobile air-condition, it is the key technology with a good prospect in the turning of electronic automobile control to the advanced stage.
