Parametric Controller Design and Optimization for a Brushless DC Motor System
Authors: , ,
Abstract: In this paper, a research on the design of parametric controller has been presented for a brushless DC motor system, and the parameters of controller are optimized. Compared with PID, the overshoot of state curve is smaller, and the settling time is shorter. The symbolic computation and the cylindrical algebraic decomposition (CAD) are used in controller design and controller parameters calculation. Symbolic computation is applied to obtain the stable constraints for the controlled system. And the region of controller parameters can be solved by CAD, according to the constraints. The parameters of controller selected in the region will stabilize the brushless DC motor system. And then, the system dynamic performance can be optimized by a variable parameter control of designed controller. The simulation results indicate that the proposed method is highly effective in controlling the brushless DC motor system.
