| Research Abstract |
Purpose of this study is to establish new sensorless drive control methods mainly for synchronous reluctance motors. The original plan of this study can be summarized as follows.
1) Establishment of dynamic mathematical model that takes flux saturation into account or is robust against flux saturation.
2) Establishment of observers for estimating rotor phase such as state-observer and disturbance-observer, which are based on the dynamic model in 1) and are expected to operate in the low to middle speed range.
3) Establishment of sensorless vector control methods using the phase estimation method in 2) for the low to middle speed range.
4) Establishment of new high frequency voltage injection methods, which is based on the mathematical model in 1) and isexpected to estimate properly rotor phase in very low speed range including standstill.
5) Establishment of a sensorless vector control method using the phase estimation method in 4) for the very low speed range.
6) Establishment of new sensorless vector control method that will operate properly in overall speed rage by make the "frequency hybrid" by both sensorless methods in 3) and 5).
The following fruits are obtained.
For plans 1) to 3), the original purposes are almost attained. However, for plan 3), sufficient data through experiments havenot been obtained due to delay of prototype fabrication of synchronous reluctance motors. The experiments is lasting.
For plans 4) and 5), the original purposes have been attained, but using permanent-magnet synchronous motors capable of producing reluctance torque instead of synchronous reluctance motors, because of the fabrication delay.
Plan 6) can be performed after completion of plan 3). In other words, it has not been done until now. It will be carried out after the completion of plan 3).
