This paper explains simulation works carried out to evaluate the performance of proportional-integral-derivative-based (PID-based) controls in controlling the electro-mechanical friction clutch (EMFC) for engagement and disengagement. The EMFC model is developed in Matlab/Simulink comprising DC motor s model and power screw mechanism s model. Four controls; proportional-integral (PI), proportional-integral-derivative (PID), proportional (P) and proportional derivative (PD), are applied on the model using 6 mm as the set point for the power screw s position. Among them, PD control performs the best with 0% overshoot, 0.041 mm steady state error and about 1.3 seconds settling time. Next, the PD control is updated with a conditional integral controller (PDPCI), resulting in approximately zero steady state error and only 0.68% overshoot, while settling time stays at 1.3 seconds. Subsequently, both PD and PDPCI controls are simulated to achieve EMFC s full engagement and disengagement. The final results show that PDPCI control performs the best with minimum overshoot.
