Frequency-hybrid vector control for sensorless induction motor and its application to electric vehicle drive
説明
As one of most useful sensorless vector control schemes for an induction motor drive, the frequency-hybrid (FH) vector control scheme has been proposed by one of the authors, which has the following high performance attributes: (1) it can make machines to produce more than 200% rated torque at standstill; (2) in both motoring and regenerating modes, rated torque can be produced even in very slow speed range including zero-speed and zero-frequency; (3) it accepts inertia larger than 200 times of rotor; (4) it has high tracking ability to variable speed command; (5) it can accept zero-speed command and settles the machines at a stable standstill with no vibration; and (6) it accepts instant injection of rated load even for zero-speed control. Most of the above performance is required for realization of a sensorless electric vehicle (EV). This paper presents design, realization and field test results of a radical new sensorless EV based on the EH vector control scheme, and clarifies its usefulness.
