查询词典 speed change

The first control strategy has the disadvantages such as a large amount of computations, inherent pull-out torque, difficulties in realizing the adaptive control and so forth. For the rotor flux-oriented control, changing of load or the rotor speed will result in increased or decreased torque winding currents, which will change the magnetic field distribution in the air gap. Assumption that magnetic field is approximately equal to that generated by torque windings will affect the levitation performances.

分析表明：气隙磁场定向控制中存在最大转矩限制、非线性机械特性，难以实现自适应控制等问题；对转子磁场定向控制而言，当负载或转速变化时，由于转矩控制绕组转矩电流变化将导致气隙磁场发生改变，如果仍以转子磁场近似替代气隙磁场作为悬浮依据，必然影响到悬浮控制性能。
