Decoupling Control of Dual Mechanical Ports Machine With Spoke Type Permanent-magnet Arrangement
摘要
Abstract
The dual mechanical ports machine (DMPM) with spoke type permanent magnet (PM) arrangement is a new type of DMPM. Its unique electromagnetic coupling characteristics are beneficial for the improvement of system performance, but the coupling between its inner motor and outer motor also makes it difficult to control in the meantime. In allusion to the control problem in DMPM with spoke type PM arrangement, the decoupling control of its inner and outer was researched in this paper. Firstly, based on the mathematic model of DMPM with spoke type PM arrangement, it was theoretically proved that the inner motor and the outer motor could be controlled by the direct torque control (DTC) method in spite of the electromagnetic coupling between them, and the condition which should be met in control was derived according to the requirement for monotonic relationship between the load angle and the electromagnetic torque; and then the decoupling control between the inner motor and the outer motor of DMPM with spoke type PM arrangement was accomplished based on space vector modulation direct torque control (SVM-DTC) method. The results of verification experiments show that the independent torque control for the inner motor and the outer motor is realized, i.e., the decoupling control between them is realized.关键词
