摘要
电机单相开关损毁后,电机仅能控制另外两相电力开关,此时若仍使用原来的三相控制系统,将会导致另外两相开关损毁,一般的d-q二轴控制便不再适用.针对上述问题提出了一种新型的单相电流调节技术,此项技术能于某相开关无法工作时,使用单相电流调节法使电机处于恒定转速状态下.结合M atlab仿真,验证了该技术的可行性.
This paper presents a new type of single-phase current regulation technology to drive the motor. This technology is applied to single-phase electrical switch damage, only two other motors control of the power switch. At this time, if still use the original three-phase control system, the general d-q two-axis control would not be suitable. It is too large to continue the current system with further speed control. In short period of time, two others can lead to damage of the switch. Therefore, this paper gives a new single - phase current adjustment phase. If the switch of one phase can not work, the use of this method makes motor control in a constant state of speed. Simulation results show feasibility of the method.
