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
