| 内容記述 | Permanent magnet synchronous motor has been widely used in variable speed drive system for various fields, such as industry, household applications, etc., The merits of PMSM are rugged construction, high efficiency, high torque to current ratio, low inertia, etc. Recently, PMSM driven air-conditioners and refrigerators are obviously increased. However, the compressors used in the air-conditioners have the problem that vibration occurs due to the torque pulsation. The frame vibration results in adverse effects, such as mechanical damage, acoustic noise and deterioration of control performance, etc.. Therefore, the vibration suppression control of PMSM driven compressor has been demanded. As a method of vibration suppression, a rubber vibration insulator has been applied. However, anti-vibration rubber is affected by the environment, such as temperature, etc.. There are disadvantages, such as short usage life, etc.. In the earlier research, several solutions have been presented based on either additional sensors, such as accelerometers, position sensors, etc., or advanced control techniques, such as the internal model principle, etc. However, the use of sensors includes negative aspects such as high-cost, more space and low reliability. As a result, the research on sensorless skill is a hot point. In the prior studies, the vibration suppression technique by a repetitive control with Fourier Transformer (FT) have been proposed. A compensation signal for vibration suppression is generated from the signal detected by the acceleration sensor and performs vibration suppression control by being superimposed to the torque current reference of the PMSM. However, in the conventional technique, it is necessary to install an acceleration sensor to detect frame vibration. As the same time, the position sensor is required to detect the rotor angular position of the PMSM. Use of these sensors depends on environmental constraints, such as temperature and installation space. High cost is also one of the reasons why it’s not preferred. In this study, a novel frame anti-vibration control method which is called Specific Component Reduction Control (SCRC) is proposed. In this method, a position sensorless speed control system is built using the Extended Electromotive Force (EEMF) observer. Then, the estimated velocity is used for generating a compensation signal in SCRC through a Fourier Transformer, to achieve the vibration suppression control without the position sensor or the acceleration sensor. Here, the conventional technique to generate compensation signal has been the repetitive controller. However, this method has a large gain in high frequency regions. The high frequency noise include in the estimated position. This noise with the position sensorless control has been increased although the desired frequency component of the vibration has been detected by FT. In this study, a new vibration suppression control method (SCRC) that takes the replace of the repetitive controller is proposed. In SCRC, the extracted vibration frequency component by the FT is learned by the integrator to generate the compensation signal. SCRC is quite difficult to amplify the noise for performing a compensation signal generation using the estimated position information. The stability analysis is also carried out. In addition, there is the possibility to perform the vibration suppression control in variable speed and the mechanical resonance point vicinity in the future. The proposed control method has the following features: (1). In our system, the estimated speed from EEMF observer has been taken as the input of SCRC. As a result, accelerometer is not necessary in the whole system. (2). The Fourier Transformation (FT) has been applied in SCRC. Only one target frequency component which is the same as command speed frequency has been taken into SCRC. The vibration suppression control system is easily stabilized by the adjustment of control parameters in SCRC. Since there is no positive feedback in SCRC, the high-frequency components are not amplified. (3). By proper calculation, SCRC can be performed as the form of Repetitive Controller based on the position which is not fluctuated. After simplifying the whole system, the linearized system diagram can be got. With this system diagram, Nyquist analysis is applied to design two most important parameters in SCRC. The target frequency harmonics component which is the same as the command mechanical speed frequency can be effectively eliminated by SCRC. (4). The experiment is carried out in the different constant speed regions, and speed variable control is also achieved with the proper design of parameters in SCRC. (5) SCRC has been developed, not only for the first-order frequency component of the estimated speed signal, but also for the second-order one. It shows that SCRC can be taken into practice of multiple components application. This controller is named as Multiple Specific Component Reduction Controller (M-SCRC). The position sensorless method, using a low-pass filter and the Extended Electromotive Force Model can’t estimate zero speed. As a result, a huge speed estimation error happens in the very low-speed region due to the parameter error and model error of the motor. The PMSM parameter estimation and new position sensorless method will be developed for the very low speed in the near future. | |||||||
