The characteristics of industrial process control systems are nonlinearity, time variability and uncertainties during variable operations. For complex nonlinear systems, a T-S fuzzy system modeling based on compatible relation is presented in the paper. The cluster analysis algorithm based on compatible relation can calculate the best cluster subset and number of the subset at the same time. The algorithm...
Since deregulation of power industry and wide use of network, there are a lot of new problems in automatic generation control (AGC) system. One is the nonlinearity of the valve position limits. The other is random time delay and data dropouts of the communication network. These factors lead to longer settling time and larger overshoot, even frequency deviation of power system. Therefore, to keep system...
A performance assessment criteria is put forward for the performance assessment of the output probability density function (PDF) control of the bounded stochastic system. The model of the output PDF is set up firstly, then the controller is designed to make the output PDF to trace the given shape so as to make the system to be a closed-loop one. The operating data of the closed-loop system are used...
