Considering the persistent disturbances and the restraint of control variables in multivariable time-varying systems, an approximate singular optimal control method is presented, which makes use of a non-singular control problem instead of singular one. Firstly, this method presents the sufficient and necessary condition for the existent of non-singular optimal control law. Then the approximate optimal...
Considering the characteristics of time delay, time variables and variable operation condition in process control system, The partial models are built based on the different operating points integrating fuzzy membership function with weighted sums to improve the traditional internal model control(IMC), and the fuzzy membership functions are obtained by recursion identification method. Then multiple...
