The 鐐 鼷 decided by Ye Ming (please read the precautions on the back before filling out this page) To solve the conventional induction « The problem of the control device of the dynamic control is that the proposed control device for the induction moving socks (Japanese Patent Laid-Open No. 5-30792 «) is constructed as above, when the primary resistance of the induction path constant of the induction machine is Ri, Once the self-inducted Li · traction coefficient σ (= 1-Μ 2 / (L 1 L 2) and other set values R 1 *, L 1 *, < r * are equal to their true values, the internal The actual value of the primary magnetic beam is the same action as the set value of the primary magnetic beam obtained by multiplying the excitation command value and the self-induction of the induction motor, so that insufficient torque or side current will not occur, and the control induction can be constantly stabilized "Rotation speed of moving eaves. Here, the control device of the induction electric eaves is to set the required rotation constant of the induction movement, that is, the primary resistance is 1? 1, the primary self-induction Li, and the leakage drag coefficient σ (= 1-M2 / (LiL2)) Generally, it can be obtained from the design of an induction motor or from constant constant tests such as resistance measurement test, restraint test, and no-load test. However, although the induction design made for the same design harms the dynamic constant, there is a considerable discrepancy due to manufacturing errors. When the design stub is not obtained, a constant measurement test is performed on each induction electric eaves of the running object. Printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs, it is not based on the usual fixed excitation «Lianzhuan command, but also variable excitation, weakening excitation, etc. to change the excitation current command_ 行 的 控 W, in this case Due to the influence of magnetic saturation, its primary induction greatly changed. At this time, if the set value of the self-induction is different from its true value, the error electric roller component Ierr obtained by (8) will have a constant sugar difference. When the error caused by a self-induced setting error is large, and the constant deviation of the component I · "occurs a lot, the output current is smaller than the ideal state and there is a situation of insufficient torque. The paper standard is applicable to the Chinese national standard ( CNS) Α4 specification (210X297mm) Ϊ0 317047 A7 B7 V. Description of the invention (n) Therefore, the control device for inducing swift motion may need to actually measure and memorize a troublesome operation of self-induction change curve. In the case of an induction motor with a closed shape, when the primary and secondary encircling currents are large, magnetic saturation occurs and the leakage coefficient is greatly changed. If the set value of the leakage coefficient is very different from its true value, Especially under heavy load conditions, a large amount of steady anchor difference will occur in the error current component Ierr obtained by formula (8). If the steady deviation of the error current component Uu occurs in the negative direction, the d axis will be obtained by formula (1) The component of AVid for compensating the pressure of AV sleeve is smaller than the ideal value and there is a situation of insufficient torque. It is very difficult to measure the curve of the leakage drag coefficient due to the saturation of magnetic gas. The control device cannot remember the change curve of the leakage coefficient when driving the induction motor with a large change in the leakage coefficient. Therefore, the setting error may cause insufficient torque.

Once again the resistance, the control device in the above proposal also compensates its Sfe and can control the load under normal lotus rotation. However, because of It does not consider the condition of the regenerative load. For example, it is suitable for special loads that require a large amount of low-speed regenerative torque when the load is raised and lowered. There is insufficient torque in the low-speed regenerative load. -The "Control Method of Induction Motor" shown in Gazette No. 299493 also describes the method of premium compensation with the value of the primary resistance. In this control method, the pressure of the pressure sensor detected by the pressure sensor and the pressure sensor is used to calculate the secondary intersecting magnetic flux, and the compensation is based on the amplitude deviation between the command value and the calculated value. However, the conventional technique used here is to subtract the voltage drop of the primary circuit from the terminal voltage of the motor, and use this as the time to calculate the two paper standards using the Chinese National Standards (CNS) A4 specification (21〇Χ2.9_7 %) ~ 317047 A7 B7 Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V.
