Pitch Motion Control of High-altitude Test Turntable Based on Electro-mechanical-hydraulic Co-simulation
Considering the load imbalance and the coupling between the hydraulic cylinders,the rigid-flexible coupling dynamics model and the electro-hydraulic control system model of the three-dimensional pitching turntable of the high-altitude test turntable were constructed by Adams and AMESim respectively.The PID control algorithm was used to co-simulate the working conditions required by the technical indicators of the test turntable pitching system.The results show that the actual angle of the pitching platform can track the angle command well and meet the requirements of orientation accuracy,which lays a theoretical foundation for subsequent experimental research.The method makes up for the deficiency that a single simulation software cannot perform a complete simulation of the system,and more accurately reflects the real control and motion state of the research object,which has universal applicability to complex electromechanical-hydraulic integrated systems.
