Abstract:

This paper analyzed the demand of accumulator control under five conditions,adopted open-loop and closed-loop control method.To the characteristic of accumulator control,designed PID control method based on feedforward compensation.For improving the accuracy of PID control and decreasing the difficulty of parameter tuning,adopted multi-group PID parameters.Though experiment,tested the result of accumulator control under high idle condition and low idle condition,and the gap of control value and feedback value is lower 1.7%.

Key words: accumulator control;feedback control;proportion control;integral , control;differential control
