卫星系统中的混沌控制

Control of Chaotic Oscillations of a Satellite

对于非线性扰动系统对指令信号的跟踪问题,提出解析条件和实现方法.对在反馈中包含线性动力和非线性两部份的非线性扰动设备进行了研究,设备的非线性部份和扰动是未知的但是有界的.提出控制卫星天平动角的算法,用图示对该算法作了说明.

Analytical conditions and practical methods of their realization are proposed to solve a problem of a command signal tracking for a nonlinear disturbed system. Nonlinear disturbed plants consisting of linear dynamic block and nonlinear block in feedback were considered. Nonlinear part of the plant and disturbance are unknown and bounded. A possibility of applications of proposed algorithms to control libration angle of satellite was illustrated.
