Sistema de acionamento com motor de indução orientado indiretamente pelo campo com adaptação MRAC da velocidade

Abstract

Este artigo investiga o uso da estratégia de controle adaptativo do tipo modelo de referência para sistemas de acionamentos de motores de indução com o controle orientado indiretamente pelo campo. O esquema proposto não requer o uso de nenhum sensor eletromecânico e é praticamente independente da constante de tempo rotórica. Por exemplo, este esquema é bem adequado para aplicações onde não há controle de velocidade, mas é necessário manter o controle com orientação indireta pelo campo sintonizado para se obter controle de conjugado com alto desempenho. A sensibilidade paramétrica do esquema de controle à variações em r s e sigmal s também é investigada no artigo. Os resultados experimentais apresentados demonstram o perfeito funcionamento do esquema proposto.<br>This paper investigates the use of the model reference control strategy for induction motor drive systems based on indirect field oriented control principles. The proposed control scheme does not require the use of any electromechanical sensor and is fairly independent of the rotor time constant. For example, this scheme is well suited for applications where there is no speed control but it is required to keep the indirect field oriented controller permanently tuned to obtain a high performance torque control. The parameter sensitivity of the control scheme to changes in r s and sigmal s is also investigated in this paper. Experimental results are presented and demonstrate the correctness and feasibility of the proposed methodology

Generalized predictive control robust for position control of induction motor using field-oriented control

“…Additionally, in [3] uses a strategy predictive applied to the direct torque control (DTC) to decrease flux and torque ripple. Technical adaptations are widely used in [4], which uses the strategy named model reference adaptive control (MRAC) to control speed in the IM. Besides there are robust techniques of DTC to speed sensorless adjust using a predictive controller in a PI structure [5].…”

“…Additionally, a predictive strategy applied to the direct torque control (DTC) was used to decrease flux and torque ripple in [3]. Technical adaptations were widely used in [4], where a strategy called the model reference adaptive control (MRAC) was used to control speed in the IM. An adaptive technique in DTC strategy was applied in an IMs in [5].…”

Hybrid Position Controller for an Indirect Field-oriented Induction Motor Drive

“…In speed loop applications for IM drives, several studies presented predictive control strategies in order to modelling the loop dynamics, for instance [6]. A sensorless adaptive speed estimation which uses the strategy named Model Reference Adaptive Control (MRAC) is presented in [7]. Additionally, a nonlinear model predictive controller is used in the speed tracking of a linear induction machine [8].…”
