The study employed and evaluated the control system utilising the PI-SMC technique on an electrohydraulic hardware simulator. Testing involves manipulating data variations in the PI control system as a means of comparison before transitioning to PI-SMC. The PI control analysis yielded significant insights into key system response characteristics, such as stability, response time, and overshoot. Simultaneously, the PI-SMC implementation exhibited a dynamic response to changes in setpoint and ?. The system's stability, response speeds, and levels of overshoots at different setpoints and ? were emphasised through a thorough analysis. The transfer function values of each control offer valuable information about the system's reaction to the input signal. The presence of poles and zero values plays a crucial role in determining stability and responsiveness, particularly at low frequencies. While the system is generally deemed stable, the occurrence of substantial overshoots in the implementation of PI-SMC suggests the necessity for additional intervention.
