After nearly 40 years of development, the genetic algorithm in the theoretical study and practical application was a great success, this paper genetic algorithm for solving the course timetabling problem, first discussed the impact of factors in the course arrangement, the main constraints, to solve goals and difficulties, and a complete mathematical model to describe the course arrangement. Arranging multiple fuzzy goals followed by a quantitative analysis, the optimal target Arranging space. Arranging for the Study of the chromosome coding and genetic operators design, proposed fitness function is calculated. Finally, the co Platform: |

Description: In This paper, the authors propose a Sensorless Direct Torque and Flux Control (DTFC) of
Induction Motor (IM) using two approach intelligent techniques: Mamdani Fuzzy Logic (FL)
controller is used for controlling the rotor speed and Artificial Neural Network (ANN) applied in
switching select stator voltage. We estimated the rotor speed by using the Model Reference
Adaptive Systems (MRAS). The control method proposed in this paper can reduce the torque,
stator flux and current ripples and especially improve system good dynamic performance and
robustness in high and low speeds-In This paper, the authors propose a Sensorless Direct Torque and Flux Control (DTFC) of

Description: A hybrid fuzzy-PI controller for voltage source
converter based HVDC (VSC-HVDC) transmission system is
proposed in this paper. At first, the elementary model of VSCHVDC
is described. Then the fuzzy self-tuning control strategy is
proposed, in which direct current control strategy and dual
closed loop structure are designed in dq synchronous reference
frame. Independent control of the active and reactive power is
realized. Simulation results show that the designed control system
obtains satisfying performance, and the adjustments of power
flow could be achieved quicker than convention PI control. Platform: |

includs a published paper which presents new relaxed stability conditions
and LMI- (linear matrix inequality) based designs for both
continuous and discrete fuzzy control systems.To some new researchers,it s a
barrier to plot the trajactories of the fuzzy system. The codes which we uploaded could be read for reference.

Description: Implementation of Fuzzy Gain Scheduling for PID Controllers in MATLAB and Simulink
Fuzzy PID Controller in MATLAB and Simulink
An approach to tune the PID controller using Fuzzy Logic, is to use fuzzy gain scheduling, which is proposed by Zhao, in 1993, in this paper. In this post, we are going to share with you, a MATLAB/Simulink implementation of Fuzzy PID Controller, which uses the blocksets of Fuzzy Logic Toolbox in Simulink. Three examples of the reference paper, are implemented as Simulink models. For backward compatibility, the models for use with MATLAB 7.9 are provided, in addition to MATLAB R2015a (version 8.5) models. Platform: |
