The determinant method of feedback, such as positive feedback and negativefeedback, voltage feedback and current feedback, series feedback and parallel feedback, etc.
Motor and inverter can be protected by the current cut-off negativefeedback when motor is overload or locked-rotor.
当电机负载过载或堵转时，采用电流截止负反馈环节可保护电机和驱动器；

Two kinds of methods such as lead net rectification and negativefeedback rectification are proposed, which can increase the output current speed of the current amplifier.
