项目摘要

This research aims to develop a control chip, which can control a position-sensorless interior permanent magnet synchronous motor (IPM motor) drive system not only by means of one chip control but also fully digital control. The control chip provides the sensorless position estimation based on magnetic saliency, which has proposed by the head investigator. This control chip makes it possible to form a position control system or a speed control system just connecting the power cables of an IPM motor to inverter terminals. Concerning research of 2002, the investigator design and produce a main circuit to drive an IPM motor of 3.7kW and an interface board which is connected with an evaluation board carrying an FPGA including logic circuits corresponding 200,000 gates. Concerning research of 2003, a ripple detection circuit and a PWM generation circuit are developed by describing it in the hardware description language VHDL, and a control software for a DSP core which is implemented in the FPGA is also developed. Experiments using the developed drive system illustrates that position estimation circuit has a good position estimation accuracy within ±1.1 degree (electrical angle) in average value with 0.5 degree dispersion. Moreover, it is shown that the developed control chip providing the position estimation makes it possible to realize a fast position control of 20 rad/s and an electrical lock of the motor shaft (servo lock) without any shaft-mounted sensor. A developing controlled chip is applicable to other IPM motors without any parameter adjustment, and it expects miniaturization of the control circuit and prevention of incorrect operation caused by electrical noises. The investigators hope that the control chip is put into practical use.

这项研究旨在开发控制芯片，该芯片可以控制无位置的内部永久磁铁同步电动机（IPM电动机）驱动系统，不仅通过一个芯片控制，而且还可以完全数字控制。控制芯片提供了基于磁性显着性的无传感器位置估计，这是由头部研究员提出的。该控制芯片使形成位置控制系统或速度控制系统成为可能，将IPM电机的电源电缆连接到逆变器端子。关于2002年的研究，研究人员设计并生产了一个主电路，以驱动3.7kW的IPM电动机和一个接口板，并与携带FPGA的评估板相连，其中包括逻辑电路，包括相应的200,000门。关于2003年的研究，通过在硬件说明语言VHDL中描述它，开发了纹波检测电路和PWM生成电路，以及在FPGA中实现的DSP核心的控制软件。使用开发驱动系统的实验表明，位置估计电路具有良好的位置估计精度，在平均值±1.1度（电角度）以内，平均值为0.5度分散。此外，已经表明，提供位置估计的开发控制芯片使得可以实现20个RAD/s的快速位置控制和电动机轴的电锁（伺服锁）（伺服锁），而无需安装任何轴的传感器。开发控制的芯片适用于其他IPM电动机，而无需任何参数调整，并且预计控制电路的小型化并预防电气噪声引起的不正确操作。调查人员希望将控制芯片投入实际用途。
