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.

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.

Switching Control Strategy

For the distribution area with a high penetration rate of new energy, the traditional power supply system has some problems, such as a single form of power supply and low utilization of new energy. Because the multi-port energy router can realize the interconnection and complementation of multiple energy forms, it has become the key piece of equipment in the hybrid AC/DC distribution area. Nevertheless, restricted by the existing control strategy, the performance of the energy router in complex operation mode switching and coordinated control still needs to be further improved. To address this issue, the free switching control strategy is proposed in this paper. Firstly, the topology and model of the multi-port energy router are designed and established. Secondly, the operation mode of the system is analyzed, and the control strategy of each port is designed. Then, a reference power calculation method suitable for multi-mode operation is derived. Based on this, the control strategy does not need to be changed when operation modes are switched. Furthermore, the extended state observer is introduced to track and compensate for the new energy disturbance, which can improve the power quality of the system. Finally, the simulation and experimental results show that the proposed control strategy of the multi-port energy router can realize flexible and controllable power transmission among various modules in the distribution area and the free switching of multi-operation modes without changing the control strategy.
