Aiming at the problem that the internal working mechanism of the fuzzy controller is unknown, an interval type 2 (IT2) fuzzy PI/PD controller is proposed, and the analytic structure of the IT2 fuzzy controller is deduced. The Fuzzy Controller adopts Mamdani rule form and assigns only two IT2 fuzzy sets to each input variable. It

In this paper, a transformer air-cooling system controller based on programmable logic controller (PLC) is proposed to realize the control and communication functions of transformer cooling system in an all-round way. The control strategy of the device adopts the combination of the top oil temperature of the transformer and the load of the transformer to

The control problem of asynchronous motor is very important. It is controlled by an auto disturbance rejection controller, and the parameters of asynchronous motor are adjusted. The parameters are studied through experiments. This kind of simulation experiment should basically study the asynchronous motor and carry out simulation experiments through specific schemes, which can be effective.

In order to further improve the effect of industrial control, this paper introduces LabVIEW engineering development platform, and uses the friendly human-computer interface and strong data acquisition and processing functions provided by LabVIEW to carry out a detailed design of PID controller based on relay feedback. The simulation results show that the design of self-tuning

Neural network does not depend on the model of the control object. It can approach the dynamic behavior of the unknown non-linear object by learning, so it can be used in the control of three-level PWM rectifier. However, due to the requirement of fast and real-time performance of three-level PWM rectifier, the practical application of
