چکیده
A KHM multi-model predictive control method is presented based on data-driven for a sort of unknownstructure nonlinear system based on vast history data only. A database search strategy based on KHarmonic Means is given, “hard” cluster is “softening”. The similar cluster is selected, neighborhood and model parameters are determined on line according to the change of system operation point. This method can shorten searching time and improve precision of the data which used to get optimal local model. A multiple generalized predictive control strategy based on KHM is developed. The simulation test has stated the validity of this approach.

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
