Description

technical field [0001] The invention relates to the technical field of satellite control, in particular to a controller design method and a control method for a cluster satellite system. Background technique [0002] The distributed formation of cluster satellite system is an important development trend of deep space exploration in the future, and has broad development prospects. With the rapid development of my country's deep space exploration field, the accuracy requirements of deep space exploration continue to increase, which requires the deep space satellite astronomical telescope to continuously increase its caliber and scale. In recent years, in order to improve the accuracy of deep space exploration and at the same time reduce the difficulty of launching satellite telescopes for deep space exploration, people have proposed the concept of cluster satellite astronomical telescopes for high and deep space exploration. By carrying astronomical telescopes on multiple smal...

Problems solved by technology

[0003] However, there are often some insurmountable problems in the work on finite-time consensus control techniques for multi-agent systems

First of all, the existing finite-time consistency control technology is difficult to achieve precise control in terms of time control, and can only obtain an upper bound of the formation completion time, and this upper bound of time is often very conservative, far greater than the real formation formation time, As a result, there is a huge loss in control costs, which seriously affects the control efficiency

Secondly, the existing finite-time consistent control technology often uses discontinuous technology to design control strategies, which often brings problems such as controller instability in practical applications.

Thirdly, the existing finite-time consistency control technology is often carried out on undirected communication networks, and the actual communication network is more of a directed communication network, which makes it difficult for the existing finite-time consistency control technology to be used in directed communication networks. use on

Finally, the existing finite-time consistency control technology is only suitable for low-order dynamical systems, and it is difficult to apply to general high-order systems
