Abstract

The invention discloses an adaptive fuzzy dynamic surface control method for a time-delay interconnected large-scale system. According to the invention, a fuzzy logic system is used to approximate an unknown time-delay function in the system, and reference signals are used to replace unknown time-delay signals in input of an approximator. The adaptive fuzzy dynamic surface control method provided by the invention for the time-delay interconnected large-scale system can process completely unknown time-varying time delay in system output, can ensure all signals in the system to be semi-global uniformly bounded, and can enable the tracking error to be converged within a small neighborhood comprising an original point.

Description

technical field

[0001] The invention belongs to the field of nonlinear time-delay large systems, in particular to an adaptive fuzzy dynamic surface control method for time-delay correlated large systems. Background technique

[0002] The decentralized control method for correlated large-scale systems has the advantages of simple design, strong reliability, and easy realization of real-time control. received widespread attention. Fang Sichen, Nasir and others discussed the decentralized control of nonlinear large-scale systems, but they did not consider the delay of signal transmission between subsystems. Due to the characteristics of the inverted pendulum such as nonlinearity, underactuation, and natural instability, the control of the inverted pendulum involves the key technology of dealing with complex objects in control science. Therefore, the inverted pendulum is often used to test whether the new control method has a strong The ability to handle nonlinear, multivariab...
