This paper deals with the direct vector control (DVC) of induction motors. It is well known that the estimation of rotor flux plays a fundamental role in the DVC and the estimation precision is significantly affected by the motor resistance. So estimation of resistance is indispensable in practice. For fast estimation of the resistance, it is necessary to slow down the convergence rate of the current...
In this paper, a simple control approach is proposed for the multi-chain systems. This method is based on a switching algorithm of two sets of smooth steering laws. Global exponential convergence of all states is guaranteed. More importantly, the convergence rate is given explicitly. Two concrete methods are proposed for the design of steering laws. One is based on the backstepping design, another...
