Research on Weighted Multiple Model Adaptive Control Based on U-Model

This article proposes a method combining the U-model and weighted multiple model adaptive control to solve control problems of nonlinear uncertain plants. The key to apply the mature linear system theory to the nonlinear system is to establish a system model that retains the form of nonlinear characteristics, which stimulates the creation of the U-model. The weighted multiple model adaptive control overrides the controlled object by constructing the model set of multiple fixed models, so as to solve the problem of uncertain parameters and parameters jump. Finally, we use the new control strategy to simulate a nonlinear system through the MATLAB software, and the results verify the convergence and stability of the multiple U-model control strategy.
