火箭发动机推力自校正控制研究
SELF-TUNING CONTROL OF VARIABLE THRUST LIQUID PROPELLANT ROCKET ENGINE
-
摘要: 由于飞行器姿态控制和空间探测任务的特殊需要,要求对火箭发动机的推力进行控制。变推力液体火箭发动机可以满足这一要求,但当发动机的推力大范围变化时,发动机的动态特性随之变化,这使得简单的反馈控制难以满足控制要求。为了改善控制品质,本文为此研究了最小方差自校正控制问题。Abstract: A self tuning controller is constructedfor a liquid propellant rocket engine with variable thrust.To verify the effectiveness of the control method,the digital simulation of controlling the variable thrust liquid propellant rocket engine with this controller is presented.The results show that the control quality of the engine system is greatly improved by the self tuning controller.
