| Abstract: | According to relevant technologies of hydraulic transmission,the construction of depth simulator was analyzed and the system was described mathematically.To meet the requirements for ocean depth simulators,the ZPETC-PID(zero phase error tracking controller-proportional-integral-derivative) controller was designed.The PID controller can improve the response speed of the system,while the ZPETC can reduce the large phase error in high-frequency response and improve the control performance of the system.A simulation on ocean depth simulator with the controller was implemented based on Matlab and the frequency response characteristics of the system were analyzed.The results show that the ZPETC-PID controller presented effectively reduces the system response errors and improves dynamic tracking accuracy of the system in high-frequency response. |
