基于零相差PID控制器的深度模拟器仿真
Simulating depth simulators using ZPETC-PID controllers
摘要
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 pre proves dynamic tracking accuracy of the sented effectively reduces the system response errors and imsystem in high-frequency response.关键词
