System control method and control system for reliability of space mechanism

Abstract

The invention discloses a system control method for use reliability of a spatial mechanism, and a control system. The method detects use reliability influencing parameters of the spatial mechanism to obtain a detection value, and an adjustment strategy is determined according to the detection value, so as to realize adjustment on control parameters of the next control period. Thus, task execution of the spatial mechanism in the next control period can be controlled. The method realizes to adjust the control parameters of the spatial mechanism in time when factors influence the use reliability of the spatial mechanism occur, thereby improving use reliability of the spatial mechanism, prolonging service life of the spatial mechanism, and reducing use cost and maintenance cost of the spatial mechanism.

Description

technical field [0001] The invention belongs to the technical field of automation control, and in particular relates to a system control method and a control system for the reliability of a space mechanism. Background technique [0002] With the development of my country's aerospace technology, aerospace application tasks are becoming more and more diverse, and space agency products are widely used, showing a diversified development trend. The overall development trend of spacecraft presents the characteristics of high value and long life. The functions of space agencies are constantly increasing, and the structure is becoming more and more complex. Especially with the increase of working time in orbit, many unpredictable new failure modes of space agencies will be exposed. . Most space agency products need to be placed outside the spacecraft cabin, which is difficult to maintain due to limited conditions. Therefore, realizing the high reliability and long life of space ag...

Problems solved by technology

[0006] In the prior art, control methods such as PID control, variable structure control, fuzzy control, neural network control and predictive control have been widely used in space mechanism control technology. In the process of space mechanism control, there are many control variables and considerations. Most of the control models only focus on the influencing factors related to the task execution effect, and seldom consider the factors affecting the service reliability related to the life of the space mechanism, and there is no one that simultaneously considers the related influencing factors of the task execution effect and life from the system level. The control method of the factors affecting the reliability of the use, which leads to the shortening of the service period of the space agency due to the influence of the factors related to the reliability of the use
