Decentralized finite-time connective tracking control with prescribed settling time for p-normal form stochastic large-scale systems

Highlights：

• It is the first time to investigate the problem of decentralized finite-time tracking control with prescribed settling time for a class of p-normal form stochastic large-scale systems with output interconnections existing in both the drift and diffusion terms.

• It is the first time to investigate the connective stability problem for stochastic large-scale systems when the system structure changes.

• Differing from the existing results, this paper proposes a new mathematical treatment algorithm to deal with the interconnections of stochastic large-scale systems, such that the decentralized tracking control is achieved.

• The proposed control strategy is more convenient for practical application than the general finite-time control.

• Due to the complexity of the system mathematics model, this paper can better reflect the application of mathematics.
