In this paper, the position control of an electrohydraulic servo system under both large inertia variations and substantial external loads has been studied. For this purpose, the Time Delay Control (TDC) was applied to the aervo system and a stability analysis was made. The results of experiments show that TDC controller achieves a fast and accurate control under inertia variations over wide range of up to about 20 times the design value, and large external loads, thereby proving its robustness. The comparative study with a well-tuned PID control shows that the system with TDC is the faster and the more accurate.
