A new control method of heart pump drive system based on neural network control

In order to satisfy the special requirements of the artificial heart pump designed by brushless DC motor, this paper presented a pulsating control system which can mimic the rhythm beating of the natural heart. It was modeled and simulated by adapting an intelligent algorithm of neural network PID. The results proved that, neural network PID control could effectively solve the problem that the parameters of the traditional PID control were difficult to be determined and the uncertain problem of the environmental disturbance. Besides, it had very good dynamic and static properties.
