Abstract

The invention provides an apparatus and the methods with on-line parameters tuning for sensorless speed control of induction motors. The proposed synchronous speed estimator offers the required feedback information of induction motors of vector-controlled inverter such that the costly speed sensor can be removed. Moreover, the proposed rotor resistor estimator adjusts the rotor resistor on-line, thereby reducing the error of system response and improving the instability; both are caused by the temperature rising under the circumstances of long-term operations or heavy loading.

Description of the invention (/) [Industrial application fields and conventional technologies] The present invention is a non-measurement induction motor speed control device and rule with online parameter adjustment. The inverter drive system of the variable speed induction motor has no regrets for the proposed motor speed control device and rules. Inverter drive systems of traditional variable-speed induction motors generally use general-purpose open-loop inverters: they drive and control the motor with a constant voltage / frequency (V / f) ratio control method, which will easily drive the induction motor to change the speed At present, it is widely used in industry. It has the advantages of small size, low price, and no need to install a speed sensor. However, it has the following problems: (1) the starting torque is limited: (2) the response The speed is slow; (3) The motor speed cannot be controlled accurately, so it is only suitable for occasions with low requirements for mechanical motion performance. The closed-loop inverter using the vector control method can improve the shortcomings of the open-loop inverter and achieve high performance. Speed control requirements, but the closed-loop frequency converter must be equipped with a speed sensor to measure the speed of the motor as the system's feedback. After the induction motor is equipped with a speed sensor, the induction motor mechanism is simple, robust and The advantages of low price and so on reduce the application scope of the induction motor closed-loop inverter. Motor closed-loop vector control inverter, whether the calculation of its vector control rule is accurate, is directly affected by the electrical parameters of the motor. Generally, the electrical parameters of the motor are measured off-line. Although accurate electrical parameters can be obtained, when the motor is reloaded or run for a long time, the temperature will increase, which will cause the motor resistance parameters to change. On-line adjustment of the motor resistance parameters will make the closed-loop paper size applicable to the Chinese National Standard (CNS) A4 specification (21〇 > < 297mm) t 锖 Read the precautions on the back before filling (This page)-Printed by the Central Standards Bureau of the Ministry of Economic Affairs and printed by the Shellfish Consumer Cooperative ^ 4 4 1 16 'a?

In view of the above circumstances, the creator of the present invention has developed a non-measurement induction motor speed control device and rules with online parameter adjustment. Using the proposed synchronous speed estimator, the speed feedback signal required by the induction motor vector control inverter can be provided without installing a speed detector; the on-line rotor can be made by the proposed rotor resistance estimator Adjusting the resistance parameter can reduce the system response error and instability caused by the change of the motor resistance parameter due to temperature rise when the motor is loaded or running for a long time. It makes the system have the advantages of both the simple and low price of the traditional universal open-loop inverter and the high performance of the closed-loop inverter. [Invention] The main purpose of the present invention is to propose a method for estimating the synchronous speed of an induction motor. It is based on the basic vector control architecture of the induction motor, and estimates the synchronous speed of the induction motor for the speed feedback signal of the inverter, thereby achieving the purpose of measuring the vector control inverter without induction motor. Another object of the present invention is to propose an induction motor stator and a method for real-time estimation of the resistance parameters of the induction motor on the line under the basic vector control architecture of the induction motor for the inverter to adjust the parameters online, so that The vector control inverter for measuring induction motor is not affected by the temperature rise of the motor. A second object of the present invention is to make the non-measurement induction motor vector control inverter achieve universal use.
