Robust Control of High-pressure Pneumatic Pressure Servo Systems
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.
