BriefIntroduction:
The conventionalnonlinear control theory usually requires that the analytic mathematical modelis known, which seriously restricts its industrial application andpopularization. The intelligent control method, mainly composed of fuzzy theoryand neural network, provides a feasible answer to the above-mentioned problem.
First, based on anew fuzzy model,fuzzyhyperbolic model (FHM),fuzzy H∞controller using linear matrix inequality technique,designing idea and designing method of filter is proposed; the sufficientconditions for the global asymptotic stability of the linear system and thesignal estimation method for the discrete nonlinear systems with multiple timedelays are established. Therefore, a large number of difficult problems inindustrial processes such as real-time online modeling, poor robustness andcomplex designing of control and filter are solved.
Then, according tothe wholly unknown or partially known system model of the nonlinear system, theneural network adaptive iterative control method is proposed, which has solvedthe long standing scientific problem that Hamilton - Jacobi - Berman (HJB)equation is difficult to obtain the analytic solution directly. Through deep analysisof the inner mechanism of the adaptive iterative control algorithm, theiterative simplified analytical solution of HJB equation is found and theadaptive optimal control theory framework of neural network with multi-dynamicperformance index is established.
