Controller Tuning Using a Cauchy MutatedArtificial Bee Colony Algorithm

摘要

Permanent Magnet Synchronous Motors (PMSM) are immensely popu-lar because they can meet the huge capacity needs of industrial applications. Speedregulation of PMSM Drives with conventional Proportional-Integral (PI) regulatorreduces the speed control precision because of the disturbances in Motor and loadcharacteristics, leading to poor performance of whole system. The values so ob-tained may not give satisfactory results in a wide range of speed. In this research,we considered the Mathematical model of speed controller for controlling the speed,which can be formulated as an optimization problem subject to various constraintsimposed due to motor and other limitation factors. For solving this problem we useda modified version of Artificial Bee Colony (ABC) algorithm known as Cauchy Mu-tation ABC (C-ABC). We first illustrate the proposed method using various standardbenchmark functions and then it is used for tuning PI controller for speed regulationin PMSM drive. Empirical results obtained are compared with the basic version ofABC, which clearly indicates the superior performance of the C-ABC algorithm.
