“…This motor is commonly used due to its adaptability to various load conditions, simple and durable structure, and affordable acquisition and maintenance [1]- [3]. Due to the vector control system's improved dynamic response [4]- [11], numerous studies in this area have been performed. Scalar control [12]- [14], however, produces the same results with low steady-state error.…”

An easy sensor-less scalar control algorithm is described in this article as a method for controlling the speed of an induction motor. For developing a closed-loop v/f control of the induction motor drive, a torque controller with PI is implemented. The torque command was estimated by utilizing the voltage command, the feedback current, and a torque estimator. Additionally, a torque reference was provided for the Torque PI controller. Considering this, the purpose of this work is to investigate the closed-loop PI-based torque control of an induction motor drive that applies DPWM. In addition to this, it provides a description of a PI-based closed-loop torque control that works in conjunction with v/f control and tries to discover the most effective method for driving an induction motor based on an examination of Total Harmonic Distortion (THD) and torque ripple. To evaluate the performance studies of open- and closed-loop strategies with DPWM techniques for induction motor driving, the MATLAB/Simulink environment has been deployed. Experimental results have been validated.

“…trole vetorial e controle direto de torque, já que estes produzem melhores respostas dinâmicas (Bim, 2001;Cruz e Paredes, 2003;Karanayil et alii, 2007;Paladugu e Chowdhury, 2007;Singh et alii, 2007;Uddin et alii, 2007;Maiti et alii, 2008;Zidani et alii, 2008). Em contrapartida, o controle escalar (El-Saady et alii, 1994;Tae-Chon et alii, 2001;Islam et alii, 2005) apresenta uma estrutura mais simples, cujas principais características consistem no seu baixo custo de implementação e no erro de regime permanente reduzido.…”

Este trabalho apresenta uma metodologia de implementação de algoritmos com estratégias fuzzy para sistemas embarcados em processadores digitais de sinais, cujo propósito de aplicação consiste no controle escalar de motores de indução trifásicos. A estratégia de controle adotada reside no ajuste da amplitude e freqüência (V/f) do sinal fundamental da tensão de alimentação do motor de indução, que foi modulado por largura de pulso aplicado a um inversor trifásico. Para tanto, o sistema de controle fuzzy foi integralmente embarcado em um processador digital de sinal empregando-se técnicas de simplificação que visam à redução dos requisitos de memória e custo computacional. O desempenho do controlador foi avaliado experimentalmente sob condições de variação de torque de carga aplicado ao eixo do motor de indução trifásico e referência de velocidade. Análises comparativas com as técnicas de controle PI e PID foram também realizadas com o propósito de validação da metodologia proposta.
