摘要
针对某三轴液压飞行仿真转台研制中的关键技术,经过详细的建模仿真,研究压差均衡控制策略对负载变形的抑制效果和PID控制参数对负载变形的影响。经过试验验证,该方案合理可行,能取得较好的动静态技术指标,最终该同步方案成功应用于某三轴液压飞行转台。
In order to solve the key technology of one three-axis hydraulic motion simulator, modeling and simulation are deduced. The differential pressure balancing control algorithm is adopted to compensate the load defor- mation induced by the parameter asymmetry of hydraulic motor subsystems controlled by two-valve and the PID algorithm is used to improve the global performance of the system. The result of experiment shows that the project takes out the better dynamic and static performance. At last, the project is applied to one three-axis hydraulic mo- tion simulator successtillly.
