Abstract	The main objective of this work is to optimize the time domain specifications i.e., less settling time, less or NO undershoot, less or NO overshoot and less rise time. This work deals with speed control of a separately excited DC motor utilizing both linear and non-linear control methods. In linear controller we considered PID controller. In Non-linear controller we considered Sliding mode controller (SMC). The main aim of this work is to design a SMC based on variable structure system which is a robust non-linear controller and insensitive to external disturbances and parametric changes. A dynamic model of separately excited DC motor of both linear PID and non-linear SMC are implemented by MATLAB/SIMULINK for speed control. The separately excited DC motor with both PID controller and SMC controller are compared and analyzed based on time domain characteristics.
