Abstract

In order to improve the control stability of air compressor for fuel cell, an air compressor control system based on open loop I/F startup and improved sliding mode observer is designed. MPC5744P is the main control chip and INCA software is the upper computer. Aiming at the stability of the control, the startup and switching process of the open loop I/F is studied, and the angular acceleration difference between the d*q* coordinate system and the actual dq coordinate system is analyzed to get the right value range. In this paper, the traditional synovium observer is studied in the middle and high speed stage, and the piecewise composite function is proposed to replace the sign function with the discontinuous origin, which weakens the high frequency chattering. The simulation results show that the improved sliding mode observer control method can effectively improve the operation stability of the air compressor.
