Abstract – The objective of this paper is to control the angular speed ω_m in a model of a DC motor using different control strategies for comparison purpose. The comparison is made between different controllers. The controllers are closed loop unity feedback controller, PID controller and the state feedback controllers like linear quadratic regulator design based on the optimal control theory and sliding mode control. Performance of these controllers has been verified through simulation results using MATLAB/SIMULINK software.
