A Fast-Response DC Motor Speed Control System

Problem statement:In this study, a Model Order Reduction (MOR) method is proposed for reducing higher order system into lower order system. Speed controller design is carried out to the lower order system by Genetic Algorithm (GA) approach and this controller is used to higher order system. Approach: This study is used to find a solution to a given objective function employing different procedures and computational techniques. The problem area chosen is that of lower order system modelling used in design of speed controller for Permananent Magnet Synchronous Motor (PMSM) drive. Results: Genetic Algorithm obtains a better controller values that reflects the characteristics of the original higher order system and the performance evaluated using this method are compared with the existing approximation method. Conclusion: Performance of this Speed controller has been verified through Simulation using MATLAB package.

“…The separation in turn allows independent design of the current and speed controllers and minimum interaction among these loops. However, there are a number of practical cases where the conventional configuration cannot deal adequately with robustness issues [5][6][7]. In particular, when the inner part of the current loop is subject to parameter variation, the conventional cascade scheme does not guarantee maintaining the outer loop for an acceptable performance.…”

“…In order to achieve high performance, many conventional control schemes are employed [1].However PMBLDC motor control and drives are complex nonlinear, they are still controlled with classical PI/ PI control structures, which are tuned to give good results only around a fixed operating point. Under these circumstances, to obtain the optimal response over the entire operating range, on-line adaptation or auto tuning of the controller is required, and several methods have been proposed in the last decade [2], [3,4]. This has attracted extensive researches in the field of control engineering, especially in the areas of tuning.…”

Permanent Magnet Brushless DC (PMBLDC) motor exhibits nonlinear behavior due to its friction, inertial variation, saturation and nonlinear coupling between motor current and rotor speed. Such uncertain and time varying system dynamics entitle the auto tuning speed control strategy for PMBLDC motor. The self tuning speed control of PMBLDC motor is subject to stringent problems because the usual controllers are not robust against the inertial and load variations. This paper aims to design and implement a novel auto tuning controller which is robust against load and inertial variations. Tests were performed on the PMBLDC motor simulation model, which provided valuable practical experience to implement the proposed tuning technique.
