METHOD AND APPARATUS FOR HIGH PERFORMANCE PERMANENT MAGNET MOTOR SPEED CONTROL WITH LIMITED POSITION INFORMATION |
摘要 |
<p>A control system for a permanent magnet motor having low-resolution speed measurement is taught. The control system is comprised of a speed regulator, voltage regulator and current regulator. The speed regulator uses a speed command and a measured speed for calculating a desired motor voltage; the voltage regulator uses a voltage command and an applied motor voltage for calculating a motor current command; and the current regulator uses a current command and a motor phase current for calculating a desired motor voltage for use by said voltage regulator; thereby providing a low resolution speed measurement to be used in a high performance application.</p> |
