Abstract
Position control, namely proportional-derivative (PD) control, is a quite common application on controlling of electrical motor. Proper application and tuning of this control algorithm can bring many efficiency and performance benefits with the motor controlling. However, electrical energy consumption of the control method for an electrical motor was few studied up to now, even the problem is very important for practical application. In the paper, an PD tuning algorithm of the position control was studied for saving energy consumption and maintaining high response performance for an electrical direct-current (DC) motor control. Firstly, response performances in time domain are analyzed by tuning of PD parameters for a position control system. Sequentially, electrical energy consumption of an electric DC motor in the position control system is discussed by simulating study. Finally, a multi-objective scheme to determine PD parameters is developed for saving energy consumption of DC motor, and high response performances are also achieved by the position control method.
