【Abstract】 Based on pulse width modulation (PWM) theory, a PWM controlled on-off cooling system is proposed in this paper,the cost of the cooling system is decreased and the reliability is increased. Using memory neural network (MNN),this paper describes a neural network self-learning control algorithm for the control of complex system with time-delay, and the control algorithm is used in the oil temperature control in hydraulic system, the experimental result is satisfactory, the oil temperature is controlled within 50±0. 5℃.更多还原
