    • A controller (400) for a variable-speed induction motor (498) includes field-oriented control (410, 476), which in a feedback (402) arrangement senses motor parameters to form field and torque error signals. The field error signals are processed by a first limited-state PI processor (490a), which individually limits the magnitude of the proportional component of the field voltage to no greater than the bus voltage. The field error signals are also processed by a state-limited integrator (426a) which limits the integral component of the field voltage to the difference between the proportional component and the bus voltage. A first summer (432a) sums the proportional and integral components to make the field voltage command. The torque error signals are processed by a further limited-state PI processor (490b) which individually limits the proportional component of the torque voltage to a value not greater than the available bus voltage, after the first PI processor has been given preference. The integral component of the torque voltage command is generated by a second state-limited integrator (426b) which limits the integral component of the torque voltage command so that the torque voltage command does not exceed the available bus voltage. A second summing circuit (432b) sums the proportional and integral components of the torque voltage command. The field and torque voltage commands are processed to produce the desired motor flux and torque, and a feedback loop forces the motor current to follow the commanded values.
    • 用于变速感应电动机(498)的控制器(400)包括场定向控制(410,476),其在反馈(402)布置中感测电动机参数以形成场和转矩误差信号。 场误差信号由第一限制状态PI处理器(490a)处理,第一限制状态PI处理器(490a)将场电压的比例分量的幅度单独地限制在不大于总线电压。 场误差信号也由状态限制积分器(426a)处理,该积分器将场电压的积分分量限制在比例分量和总线电压之间的差。 第一个夏天(432a)将比例和积分分量相加以产生场电压指令。 转矩误差信号由另一个有限状态PI处理器(490b)处理,在第一PI处理器被优先给定之后,其将单独将转矩电压的比例分量限制在不大于可用总线电压的值。 转矩电压指令的积分分量由限制转矩电压指令的积分分量的第二状态限制积分器(426b)产生,使得转矩电压指令不超过可用总线电压。 第二加法电路(432b)对转矩电压指令的比例积分分量进行求和。 处理场和转矩电压指令以产生所需的电动机通量和转矩,并且反馈回路迫使电动机电流遵循指令值。

    • An electric motor vehicle includes an electric motor driving a step-down differential, axles, and drive wheels. An operator control produces torque command signals, which are applied to a controller to command application of electric power to the motor in response to the torque commands, to achieve the desired torque. The low friction of the electric drive, in conjunction with the rotational compliance or imperfect stiffness of the axles, may result in low-frequency surges or jerky motion, especially at low speeds. A damping arrangement includes a differencing circuit coupled between the operator control and the controller, for taking the difference between the operator-commanded torque and a damping torque signal. The damping torque signal is produced by differentiating the electric motor speed to produce a motor-acceleration representative signal.
    • 电动车辆包括驱动降压差速器,轴和驱动轮的电动马达。 操作员控制产生扭矩指令信号,其被施加到控制器以响应于转矩指令来指示向电动机施加电力以实现期望的转矩。 电驱动器的低摩擦力与轴的旋转顺应性或不完美刚度相结合可能导致低频浪涌或跳动,特别是在低速时。 阻尼装置包括耦合在操作者控制器和控制器之间的差分电路,用于获取操作者指令的扭矩和阻尼扭矩信号之间的差异。 阻尼扭矩信号通过微分电动机速度产生电动机加速代表信号而产生。
