Their control is a difficult task because their dynamics are strongly nonlinear. Generally, vector control is used with direct axis current control. However, a problem might arise with such systems in terms of electrical parameter variations and, especially, the mechanical parameters, more specifically the inertia moment of the encircling mass. An adaptive approach is an interesting alternative, when parameters of the machine are unknown or varying in time; in order that objectives imposed by the control are reached and maintained. An adaptive control scheme is presented based on the online parameter estimation of the system or of the regulator.","PeriodicalId":143007,"journal":{"name":"ICEMS'2001.

The two subsystems: rotor speed and rotor flux, are treated as the reference model of adaptive control for the next section. An adaptive law is presented to counteract the harmful effects of disturbances, which cause the loss of decoupling and linearizing. It Is proved in the paper that the errors between outputs of reference model and control object are exponentially convergent to zero, and the system is stable. By choosing parameters, the algorithm reduces the complexity of calculation at the same time. This makes it more suitable for the speed control system performed by the high-speed DSPs. Simulations show that flux and speed are still decoupled during the transient of the system. The proposed control is suitable for high-dynamic performance applications.","PeriodicalId":143007,"journal":{"name":"ICEMS'2001.
