Depth simulator having high dynamic quality and control method thereof

Abstract

The invention provides a depth simulator having high dynamic quality and a control method thereof. After an input instruction of a host computer is received by a main computer, a depth instruction is resolved, is fed back to the host computer for display and is outputted to a PID controller, a flow instruction is outputted by the host computer to the PID controller, the flow instruction is responded by the PID controller and outputted to the host computer for display; a pressure feedback signal of a sensor in a hydraulic system is received by the PID controller, PID control is further carried out, and a control signal is outputted by the PID controller to a servo valve of the hydraulic system; constant pressure oil having pressure satisfying largest depth simulation requirements of the depth simulator is provided by an oil source system to the servo valve, and pressure is outputted by the servo valve to the external part; output pressure of the servo valve is measured by the pressure sensor, and the measured pressure signal is fed back to the PID controller. Through the depth simulator, problems generated in traditional PID control are corrected, influence of the problems on a control system can be reduced to a maximum degree, and the dynamic control process is effectively accelerated.

AI Technical Summary

Problems solved by technology

[0003] Because the large depth simulator has the characteristics of high precision and fast response, it is difficult for the traditional PID control method to obtain good dynamic characteristics due to some defects of the conventional control algorithm itself, such as integral saturation problems, anti-interference problems, dynamic process acceleration problems, etc.

In addition, due to the constraints of the non-real-time nature of the system and the limitation of the measurement accuracy and range of sensor components, it is difficult to improve the response speed and accuracy of the depth simulator.
