This paper deals with control of a DC motor using conventional and unconventional techniques namely the exploitation of artificial neural networks, fuzzy logic controller and PID controller. After studying the performances of the PID controller, the idea is to determine a partial fuzzy or partial neuronal PID controller. For the control of the position of the DC motor, an hybrid controller comb...

Received Jan 17, 2017 Revised Mar 17, 2017 Accepted Mar 31, 2017 Brushless DC motor is a synchronous machine that makes use of electronic commutation instead of mechanical commutator. Brushless DC motors makes use of inverter encompassing static switches for its operation. A simple bridge converter when used for BLDC drive as front end converter makes input source power factor to get reduced wh...

This paper presents fuzzy logic control (FLC) based speed control system for a DC Motor drive through the use of Genetic optimization. The control system design and implementation procedures of DC motor drive using Digital Signal Processor are described. Results of simulation and experimental on the real control system demonstrated that the proposed FLC is able to overcome the disadvantage of u...

The paper describes hardware implementation of control system designs using the Quanser DC Motor Control Trainer (DCMCT). Toward this goal, students are guided to design control systems and verify their designs via simulation environments like MATLAB/Simulink. Then, they realize the control system designs by building op-amp circuits and validate the designs via the Quanser DC Motor Control Trai...

Abstrac—The genetic algorithms (GA) with global optimization character and the simplex method are combined and used into the application of the parameter identification. The nonlinear dynamic model of an actual DC motor including the nonlinear friction torque is established. By means of the compound evolution algorithms proposed, the detail procedure of the all parameters identification in the ...

This paper describes vibration diagnosis based on electric faults. These faults could appear in electrical equipment in general, but this paper focuses on the case of transformer, induction and dc motor. In order to do the diagnosis there are analysed vibration signals from the piezoelectric accelerometer. This accelerometer is installed on the frame of the equipment. The signals acquired are a...

The hybrid solar and fuel-based motor produces more power by using the direct torque control. The control based PMSM fed inverter for continuous power production. The dc bus voltage is regulated by us...

When compared to other types of motors, brushless DC (BLDC) motors have, larger torque, higher speed, greater efficiency, better control, longer maintenance life and are cleaner. However, their control circuitry is much more complicated than that of an ordinary brushed DC motor, often resulting in designers’ preference for other motor types. This paper will step through the design of both the h...

This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-mmf diagram is a generaked version of the flux-linkage versus current (+i) diagram €or switched-reluctance motors. It is illustrated €or switchedreluctance, synchronous-reluctance, induction, brushless ac, brushless dc, interior PM and dc commutator moto...
