This paper deals with the vector control, including both the direct vector control (DVC) and the indirect vector control (IdVC), of induction motors. It is well known that the estimation of rotor flux plays a fundamental role in the DVC and the estimation of rotor resistance is vital in the slip compensation of the IdVC. In these estimations, the precision is significantly affected by the motor resistances. Therefore, online estimation of motor resistances is indispensable in practice.For a fast estimation of motor resistances, it is necessary to slow down the convergence rate of the current estimate. On the other hand, for a fast estimation of the rotor flux, it is necessary to speed up its convergence rate. It is very difficult to realize such a trade-off in convergence rates in a full order observer.In this paper, we propose to decouple the current observer from the flux observer so as to realize independent convergence rates. Then, the resistance estimation algorithm is applied to both DVC and IdVC. In particular, in the application to IdVC the flux observer needs not be used, which leads to a simpler structure. Meanwhile, independent convergence rates of current observer and flux observer yield an improved performance. A superior performance in the torque and flux responses in both cases is verified by numerous simulations.

“…Supondo que a velocidade é medida online e possui valores máximos e mínimos conhecidos, o sistema (34) pode ser visto como um sistema linear a parâmetros variantes, ou LPV do inglês Linear Parameter Varying (Leith e Leithead, 2000), onde ω e é a variável de escalonamento. Além disso, frequentemente, a resistência do rotor é modelada como um parâmetro incerto variante no tempo, com valores máximos e mínimos conhecidos, visando considerar no modelo da máquina as variações provocadas tipicamente pelo aquecimento do rotor (Chan e Wang, 1990). …”

Design of Flux Observers for Direct Field Control in Five Phase Induction MachinesThis paper proposes a convex optimization approach for the design of robust observers applied to the control of five phase induction machines subject to rotor resistance variation and load disturbance. Based on the first and third harmonic dynamic models of the multi-phase machine, two robust observers are proposed to estimate the rotor flux components. The two observers are applied to the direct field oriented control of a five phase induction machine, where simulation results have demonstrated a high dynamic performance and robustness to parametric variations of the proposed setup. RESUMOApresenta-se neste artigo a aplicação de técnicas de otimização convexa para o projeto de observadores robustos aplicados a motores de indução pentafásicos, sujeitos a variações na resistência do rotor e a perturbações de carga. É desenvolvido um estimador robusto para os fluxos do primeiro e terceiro harmônico do rotor, cuja validação é realizada junto ao controle por orientação de campo no modo direto admitindo aplicações que exijam elevado desempenho dinâmico e alta robustez frente a variações paramétricas e distúrbios externos.

Abstract-This paper addresses the speed and flux regulation of induction motors under the assumption that the motor parameters are poorly known. An adaptive passivity-based control is proposed that guarantees robust regulation as well as accurate estimation of the electrical parameters that govern the motor performance. This paper provides a local stability analysis of the adaptive scheme, which is illustrated by simulations and supported by a successful experimental validation on an industrial product.
