    Abstract: A control system for a motor includes a pulse-width modulation module, a pulse skip determination module, and a duty cycle adjustment module. The pulse-width modulation module generates three duty cycle values based on three voltage requests, respectively. A plurality of solid-state switches control three phases of the motor in response to the three duty cycle values, respectively. The pulse skip determination module generates a pulse skip signal. The duty cycle adjustment module selectively prevents the plurality of solid-state switches from switching during intervals specified by the pulse skip signal.

    Abstract: A current control module generates a voltage request based on a d-axis current (Idr) demand. A switching control module controls a motor based on the voltage request and generates an out-of-volts (OOV) signal based on a comparison of the voltage request and an available voltage. An Idr injection module generates the Idr demand based on a direct current (DC) bus voltage, a rotational speed, and a demanded torque and selectively applies a first adjustment to the Idr demand. The Idr injection module identifies whether an improvement resulted from the first adjustment, wherein the improvement is identified based on at least one of (i) a measured current of the motor and (ii) the OOV signal. The Idr injection module selectively applies a second adjustment to the Idr demand based on whether the improvement is identified.

    Abstract translation: 电流控制模块基于d轴电流(Idr)需求产生电压请求。 开关控制模块基于电压请求控制电动机,并且基于电压请求和可用电压的比较产生失伏(OOV)信号。 Idr注入模块基于直流(DC)总线电压,转速和所需转矩产生Idr需求,并且选择性地对Idr需求进行第一调整。 Idr注入模块识别是否由第一调整产生改进,其中基于(i)电动机的测量电流和(ii)OOV信号中的至少一个来识别改进。 Idr注入模块基于是否识别改进来选择性地对Idr需求进行第二调整。
