Abstract: High-frequency and long-running hydraulic servo system sinusoidal tests are developed for automobile engine flywheels in this article. The frequency characteristic of the hydraulic system is revealed by the classical control method and the double inertia loop. The feedforward controller is introduced so as to compare it with the adaptive control. The modified amplitude-phase adaptive control (MAPAC) method is proposed to cope with the uncertainties in the hydraulic system to increase the precision of sinusoidal experiments without knowing the structure and parameters of the system. The amplitude error, phase delay, and the center position error of the sinusoidal signal are identified in the time domain, and the iterative equations are established for these three parameters. The simulation and experimental results show that higher tracking accuracy can be achieved with the sinusoidal signal than the feedforward controller by using the MAPAC controller.
