Opis:: This paper presents some design approaches to hybrid control systems combining conventional control techniques with fuzzy logic and neural networks. Such a mixed implementation leads to a more effective control design with improved system performance and robustness. While conventional control allows different design objectives such as steady state and transient characteristics of the closed loop system to be specified, fuzzy logic and neural networks are integrated to overcome the problems with uncertainties in the plant parameters and structure encountered in the classical model-based design. Induction motors are characterised by complex, highly non-linear and time-varying dynamics and inaccessibility of some states and outputs for measurements, and hence can be considered as a challenging engineering problem. The advent of vector control techniques has partially solved induction motor control problems, because they are sensitive to drive parameter variations and performance may deteriorate if conventional controllers are used. Fuzzy logic and neural network-based controllers are considered as potential candidates for such an application. Three control approaches are developed and applied to adjust the speed of the drive system. The first control design combines the variable structure theory with the fuzzy logic concept. In the second approach neural networks are used in an internal model control structure. Finally, a fuzzy state feedback controller is developed based on the pole placement technique. A simulation study of these methods is presented. The effectiveness of these controllers is demonstrated for different operating conditions of the drive system.

Opis:: This article aims to implement the fuzzy control for an asynchronous motor after a general representation of the vector control. We develop MAMDANI type fuzzy algorithm for MAS speed regulation; it’s one purpose is to cancel static error, decrease overshoot, decrease response time, and rise time to obtain an adequate response of the process and regulation and to have a precise, fast, stable and robust system. This paper investigates the design of a fuzzy-based approach for monitoring the inversion of the rotational speed of an induction motor. We will indeed present a robust vector control technique ex-tended to blur in the event of a fault. Direct torque control is known to produce fast and robust response in the AC drive system. However, in a steady state, a rapid and unexpected change in speed can occur which could be dangerous. The performance of the conventional PID controller can be improved by implementing fuzzy logic techniques. The first step is the modelling of the whole system, including the capacitors, the induction generator and the loads. The model is obtained using the Park transformation. The results are thus compared with those of the standard PID control. This approach is applied to a three-phase asynchronous motor (LS90Lz). The presented study improves the transient response time and the precision of the servo system. An inversion of the reference speed of rotation is considered, and the results are very convincing.

Opis:: The traditional train speed control research regards the train as a particle, ignoring the length of the train and the interaction force between carriages. Although this method is simple, the control error is large for high-speed trains with the characteristics of power dispersion. Moreover, in the control process, if the length of the train is not considered, when the train passes the slope point or the curvature point, the speed will jump due to the change of the line, causing a large control error and reducing comfort. In order to improve the accuracy of high-speed train speed control and solve the problem of speed jump when the train runs through variable slope and curvature, the paper takes CRH3 EMU data as an example to establish the corresponding multi-point train dynamics model. In the control method, the speed control of high-speed train needs to meet the fast requirement. Comparing the merits and demerits of classical PID control, fuzzy control and fuzzy adaptive PID control in tracking the ideal running curve of high-speed train, this paper chooses the fuzzy adaptive PID control with fast response. Considering that predictive control can predict future output, a predictive fuzzy adaptive PID controller is designed, which is suitable for high-speed train model based on multi-point. The simulation results show that the multi-point model of the high-speed train can solve the speed jump problem of the train when passing through the special lines, and the predictive fuzzy adaptive PID controller can control the speed of the train with multi-point model, so that the train can run at the desired speed, meeting the requirements of fast response and high control accuracy.

Opis:: Aiming at the warp knit fabric horizontal strip problem faced by the multi-speed electronic let-off process of warp knitting machines, a design scheme of a fully digital intelligent multi-speed electronic system is proposed. A wide-range digital speed measurement method is proposed which solves the problem that the traditional analog circuit speed measurement method cannot measure the real-time warp beam speed, and also eliminates the problem of the low-speed feedback blind zone. According to the characteristics of the electronic let-off system of warp knitting machines, the hardware structure and software algorithm of the fuzzy PI control system were designed which can adjust the control parameters of the traditional PI controller in real time according to the fuzzy control table, and realise stable multi-speed electronic let-off. The effectiveness of the design method was verified by simulation.
Mając na celu rozwiązanie problemu poziomych pasków dzianiny osnowowej, z którym boryka się wielobiegowy, elektroniczny proces wypuszczania osnowowych maszyn dziewiarskich, zaproponowano schemat projektowy w pełni cyfrowego, inteligentnego, wielobiegowego systemu elektronicznego. Zaproponowano szeroko zakresową cyfrową metodę pomiaru prędkości, która rozwiązuje problem polegający na tym, że tradycyjna metoda pomiaru prędkości obwodu analogowego nie może mierzyć prędkości wiązki odkształcenia w czasie rzeczywistym, a także eliminuje problem martwej strefy sprzężenia zwrotnego przy niskiej prędkości. Zgodnie z charakterystyką elektronicznego systemu wypuszczania maszyn dziewiarskich osnowowych zaprojektowano strukturę sprzętową i algorytm programowy systemu sterowania rozmytego PI, który może dostosowywać parametry sterowania tradycyjnego regulatora PI w czasie rzeczywistym zgodnie z rozmytą tabelą sterowania i zrealizować stabilne elektroniczne wyzwalanie z wieloma prędkościami. Skuteczność metody projektowania zweryfikowano za pomocą symulacji.
