摘要： A system and method are provided for controlling the speed of a motor driving a load that is electrically connected to a generator driven by an engine, through use of a first control feedback loop configured to control the rotor flux of the motor by controlling the field excitation of the generator, and a second control feedback loop configured to control the speed of the motor by controlling the throttle position of the engine.

摘要： Presented is a harmonic regulator that regulates a plurality of individual harmonics in a system having periodic torque disturbances to commanded values, including zero. For each harmonic being regulated, a feedback signal having at least one harmonic component due to the harmonic being regulated is transformed from a source reference frame to a harmonic reference frame of the harmonic being regulated to form a qd feedback signal. The qd feedback signal is subtracted from the commanded value to form a qd signal and regulated. The regulated qd signal is transformed to a destination reference frame to form a compensation signal and the compensation signal is added to a control signal to form a qd control signal that drives each harmonic being regulated towards the commanded value.
摘要翻译：提出了一种谐波调节器，其调节具有包括零的指令值的周期性扭矩扰动的系统中的多个单独的谐波。对于被调节的每个谐波，具有由谐波被调节的至少一个谐波分量的反馈信号从源参考帧变换到调节的谐波的谐波参考帧以形成qd反馈信号。从命令值中减去qd反馈信号，形成qd信号并进行调节。调节的qd信号被变换到目的地参考帧以形成补偿信号，并将补偿信号加到控制信号上以形成驱动每个谐波被调节到指令值的qd控制信号。
