Frequency analysis and PID controller design for a pump-controlled electrical hydraulic system

Electrical-hydraulic servo systems are widely used in industry, and obviously a highly performance is required. In this article, a pump-controlled electrical hydraulic servo system is analyzed using PID controller. The model of the system is established, and the frequency response is analyzed in frequency domain using Simulink. Besides, simulation is carried out in real-time domain. According to the results, the system performs well both in frequency and real-time domain.
