This paper applies hidden semi-Markov model (HSMM) to estimate the network load states on the basis of time delay observations for multi-mode switching control of the NCS. The close-loop NCS with state feedback controller is modeled into a semi-Markov jump linear system (S-MJLS). Then the controllers corresponding to each mode are designed based on the stability theory of S-MJLS. Simulation results show the effectiveness of the proposed approach in this paper.

Markov Jump Linear System

This paper is devoted to investigating the stability and stabilisation problems for discrete-time piecewise homogeneous Markov jump linear system with imperfect transition probabilities. A sufficient condition is derived to ensure the considered system to be stochastically stable. Moreover, the corresponding sufficient condition on the existence of a mode-dependent and variation-dependent state feedback controller is derived to guarantee the stochastic stability of the closed-loop system, and a new method is further proposed to design a static output feedback controller by introducing additional slack matrix variables to eliminate the equation constraint on Lyapunov matrix. Finally, some numerical examples are presented to illustrate the effectiveness of the proposed methods.

According to the switch transients problem existing in the Hybrid Actuation System (HAS), a multi-mode switching control system was proposed. This control system, based on the system feedback correction theory, can cater to the demands of dynamic characteristics and switch transients. To start with, the mathematical model of HAS was established on the basic of HASs operating principle, and the HAS is composed of Hydraulic Servo Actuator (HSA) and Electro-Hydrostatic Actuator (EHA). Further, the different operating modes controller are hammered out by employed the PID feedback correction control, and the acceleration feedback controller is added to the switched system to decreasing the switch transients. Finally, simulation results demonstrate the system is precise in tracking displacement signal, and it is validity of mitigating the switch transients by used method of feedback correction.
