Robust Control of High-pressure Pneumatic Pressure Servo Systems
高压气动压力伺服系统的参数不确定性和未建模动态制约了其控制精度的提高,针对此提出了基于RISE的自适应鲁棒控制算法用于高压气动压力伺服系统的控制.考虑到核心元件高压电-气伺服阀的控制性能对高压气动压力伺服系统高精度控制的影响,设计了交叉对比实验,实验结果表明,伺服阀位置控制算法有助于避免正弦信号失真、减小稳态压力抖动,系统压力控制算法能提高系统的响应速度和动态跟踪能力.
Parameter uncertainty and unmodeled dynamics of HPPS restricted the improvement of the control accuracy.An adaptive robust control method was proposed and applied to control the HPPS based on RISE.This paper considered the influencs of HESV control performance on the high-precision control of HPPS,and a cross-comparison test was designed.The results show that the HESV position control method may avoid sinusoidal signal distortions and reduce steady-state pres-sure jitter,and the HPPS pressure control method may improve the response speed and dynamic tracking capability of the systems.
