Abstract:
This paper introduces the spec ialties of g iant te lescopem ount contro l system, analyses the non linear d isturbance wh ich reduces the perform ance of contro l system, com pa res tw o robust contro l theory and po ints out thatH -infin ity contro l theory is mo re su itab le fo r telescope mount contro l system. Based on the theoretica l fram ew ork ofH- infin ity contro:l Non-linear fr iction torque is regarded as model outpu tmu l tip licative perturba tion. The prob lem is transform ed into how to im prove sy stem robustness on m ode l per turbation and w ind load disturbance. A su itab le H-infin ity veloc ity contro ller is obtained by programm ing inMATLAB. Compu ter simu lation result shows that the contro llerw hich is designed byH-in finity con tro l theo ry im proves system robustness and the precision of track ing.
