Weak magnetic field controlled by indirect magnetic field oriented induction motor abstract -A-type self-organizing induction motor controller solves the problems encountered. The field oriented control (FOC) technology is based on the principle of model reference adaptation, but it depends on the state of the machine to determine the control input. Compared with other methods, the proposed controller is weak in field operation, and its advantages and limitations are discussed. The experimental results put forward classical and self-organized weak magnetic operation. The driving torque response speed of high-performance asynchronous motor is lower than the fundamental frequency, and constant power requires sufficient torque response at the above fundamental frequency. Vector or magnetic field oriented control (FOC) is the most successful in meeting these requirements. On the other hand, considerable energy is spent on the performance requirements of drivers in engineering design and testing applications, excluding the selection of drivers per hertz 1 volt. The complexity and cost of field-oriented asynchronous motor drive in a big country are under control (IFOC). It is necessary to define complex controllers with machine parameters, but this also leads to the lack of motivation for magnetic field orientation, which limits the robustness of specific drive induction motors. Adding an accurate current regulator reduces the complexity of 1 IFOC. The high bandwidth current loop minimizes the influence of stator parameters and reduces the precise parameters that must be related to rotor circuit, rotor resistance and rotor inductance. In addition, it is necessary but not sufficient to combine accurate current regulator to ensure current coincidence. IFOC needs to estimate the continuous decline of the machine. It is becoming more and more complicated to obtain accurate sliding, because the parameters that drive the debugging machine must be obtained from the manufacturer or pass strict tests, regardless of the machine. An automatic initialization scheme of rotor time without external constraints is proposed, and the branch gain is determined by empty search process. The program reduces the dependence on the machine and starts the debugging of asynchronous motor drivers with magnetic field orientation. Once the motor parameters are changed, the influence on the rotor resistance (such as temperature) needs to be controlled by the on-line sliding gain identifier to maintain the magnetic field orientation. Online recognition algorithm has received a lot of treatment in the past ten years [7]-[ 10]. Most of them are adaptive controllers, which use self-adjusting process to determine the parameters used in magnetic field orientation control. In addition, parameter adaptive algorithms usually assume a linear machine model and require prior knowledge of machine inductance.
