This paper, presents a Direct Field-Oriented Control (DFOC) of doubly fed induction machine (DFIM) motor mode with a variable structure control based on a sliding mode control (SMC). Our aim is to make the speed and the flux control robust to parameter variations. The use of the nonlinear sliding mode method provides very good performance for motor operation and robustness of the control law de...

This paper discusses fuzzy sliding mode controller applied for induction motor field oriented control with space-vector pulse-width modulated inverter. The speed control is obtained by controlling the inverter switching frequency determined by the reference voltage resulted by the controller. Simulation results show that fuzzy sliding mode controller performed satisfactorily and better compared...

– The demand of the non-isolated voltage-boosting converters has experienced an unprecedented augmentation in the last decade. The diversified application domains host the variety of specifications and rating on DC/DC converters and several variations has been addressed, in addition to the basic buck and boost converters. The main issue with them is presence of objectionable level of voltage ri...

This paper deals with certain aspects of operation of a third order Variable Structure System using Sliding Mode Control (SMC). SMC is applied to the process plant using LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench). The process plant and its control are simulated using LabVIEW 2011 and the results are compared with conventional PID controller. It is found that the settling...

Induction Motors have been used as the workhorse in the industry for a long time due to its easy build, high robustness, and generally satisfactory efficiency. However, they are significantly more difficult to control than DC motors. One of the problems which might cause unsuccessful attempts for designing a proper controller would be the time varying nature of parameters and variables which mi...

During the milling process, one of the most important factors in reducing tool life expectancy and quality of workpiece is the chattering phenomenon due to self-excitation. The milling process is considered as a MIMO strongly coupled nonlinear plant with time delay terms in cutting forces. We stabilize the plant using two independent Emotional Learning-based Intelligent Controller (ELIC) in par...

We propose a terminal sliding mode control (SMC) law based on adaptive fuzzy-neural observer for nonaffine nonlinear uncertain system. First, a novel nonaffine nonlinear approximation algorithm is proposed for observer and controller design. Then, an adaptive fuzzy-neural observer is introduced to identify the simplified model and resolve the problem of the unavailability of the state variables...

In this paper a Sliding mode controller (SMC) scheme based on the power rate reaching law approach has been proposed for the inner loop current control of the 3-Phase Brushless DC motor (BLDC) drive. A proportionalintegral (PI) controller is used to control the outer loop speed performance. The developed PI-SMC control scheme is simulated on MATLAB/SIMULINK platform under a sequence of load tor...

The sliding-mode controller (SMC) for the lateral motion control problem of Four Driving-Steering Wheels (4DW/SW) vehicle is presented in this paper. The lane centerline tracking is the main control performance. The dynamic model of the vehicle has been taken into account. Closed-loop robustness to uncertainties is achieved. The lane centerline tracking is achieved using look-ahead techniques. ...
