DESIGN AND ANALYSIS OF CONTROLLER FOR MOTION CONTROL SYSTEM

In motor drive applications, the mechanical properties of electrical motor under various load and operating conditions are different. These changes highly influence the performance of motor drive systems as the system's dynamic response under these variations is affected. This project presents the design and development of a system controller for motion control system. The basic approach used in this project is by using the modem control engineering theory through the state space approach. The state space design approach was used instead of the conventional control because state space design is most suitable for nonlinear system and multi-input multi-output (MIMO) system set-up. In the initial stage, the controller system for motion control system was designed using the linearized equation of motion. For this motion control system, the load torque was selected as the input with mechanical angnlar position as the output. This project consists of modelling and simulation using Simulink, and performance evaluation is done through the system analysis. A satisfactory performance is achieved from the designed controller system which is better than the conventional control in terms of controllability, observability and stability to be used in motion control system
