This paper presents an improved performance of a Permanent Magnet Synchronous Motor (PMSM) using a hybrid Fuzzy/ Proportional-Integral (PI) controller. Hybrid control has an advantage of integrating a superiority of two or more control techniques for better control performances. A fuzzy controller offers better speed responses for start-up and large reference input changes (large speed error) as compared...
For the multi-motor synchronous control system has time delay and stochastic disturbance and uncertainty model factors, this paper proposed a fuzzy Smith controller which combined Smith pre-estimate control and fuzzy PID control, introducing the structure, the design method of the speed controller and modeling of the control system. Matlab toolboxes are used to simulate the multi-motor synchronous...
Based on the rebuilt of control rule base, a modified type PI-like fuzzy logic controller (FLC) with output scaling factor (SF) self-tuning mechanism is proposed in this paper for application in the switched reluctance motor (SRM) drive system. This paper intends to simplify the construction hierarchy and computational complexity of the controller by trimming the number of fuzzy sets in the membership...
This paper presents the position control of a DC motor using Fuzz Logic and PID Control algorithms. Fuzzy Logic and PID controllers are designed based on labview program, and the real - time position control of the DC motor was realized by using DAQ device. The experimental results demonstrate that the responses of DC motor with FLC show a satisfactory, well damped control performance.
The severe nonlinearity of translation meshing motor (TMM) make it hard to get a good control performance with conventional proportional-integral-derivative (PID) controller. In this paper, an intelligent PID controller based on fuzzy logic for TMM drive system is developed. The parameters of the proposed controller are tuned online according to fuzzy logic tuning rules which are summarized from the...
This paper presents two feasible realizations of 2-DOF wide-range speed control schemes for combustion turbogenerators. These schemes allow independent tuning of the reference tracking and disturbance rejection characteristics of the control system. The fuzzy approach extends these characteristics throughout the operating space of the combustion turbogenerator. Both realizations can be inserted into...
Based on the redevelopment of control rule base, a modified type PI-like fuzzy logic controller with output scaling factor (SF) self-tuning mechanism is proposed and experimentally testified in this paper for application in the switched reluctance motor (SRM) drive system. This paper aims to simplify the structure hierarchy and computational complexity of the controller by reducing the number of fuzzy...
PID controllers are very common in industrial systems applications. Tuning of parameters of the controllers is governed by system nonlinearities and continuous parameter variations. In this paper, a complete and rigorous comparison is made between two tuning algorithms. PI controller was used in a speed control loop through a field oriented Control (FOC) of an induction motor. AC machine was primarily...
