This paper presents a grey–fuzzy predictive controller that is based on fuzzy theory, grey prediction and on-line switching algorithms. The grey predictor is applied to extract key information and reduce the randomness of the measured non-stationary time-series signals from sensors, and send the prediction information to the fuzzy controller. The complete(More)
The network-induced delay is the critical issues of NCS design. In this paper, the novel real-time optimization grey prediction method, based on the research of grey theory and optimization theory is proposed for modeling the network-induced delay. It needn't know statistical characteristic. By using AGO to smooth the original data sequence, the random(More)
The main objective of this paper is to demonstrate the feasibility of Internet-based remote monitored control system for teaching. An open-loop unstable dual-parallel coupled inverted pendulum platform is constructed and uses to develop the NCSs with real-time application interface. Client-Server architecture is developed with the network communication for(More)
This paper presents a novel iterative learning control method based on the research of grey theory. The grey predictor is applied to extract key information and reduce the randomness of the measured non-stationary time series signals from sensors, and send the prediction information to the iterative learning controller. This design can not only reduce the(More)
This paper investigates H∞ stabilization criterion for uncertain MIMO networked control system with disturbance, where its network transmission is connected with network-induced delay and packet dropout both sensor-to-controller and controller-to-actuator. In order to obtain much less conservative results, the criterion is analyzed by using 2nd(More)
The precision of gyro is one of the most important points to decide precision of inertial navigation system and it is mostly effected by the gyro random drift. A kind of BP adaptive fuzzy method using minimum standard deviation estimator to identify gyro random drift is proposed in the paper, and the mathematical model is established. It makes the best of(More)
