A Non-Iterative Controller Design for a BLDC Drive System

Brushless DC (BLDC) drive systems find immense applications in control systems. One such application is position control that requires very good stability limits, steady state and transient responses. Hence brushless dc drive systems should respond to meet these requirements. In this paper, few BLDC motor drive systems are considered. It is found that such systems cannot yield desired performance when conventional controller design procedure is employed. Hence, a modified design methodology for controller design of such systems is suggested. Simulation results of responses of BLDC drive systems are obtained for various desired specifications. Experimental results of responses of a BLDC drive system are obtained for various desired specifications using the proposed and conventional design methodologies to justify the simulation results. It is concluded that proposed design technique is more suitable for the controller design of such BLDC drive systems. Moreover, it can be understood that the controller design technique is non-iterative.
