    • The present invention provides a method of controlling the height of a looper in an inter-stand section of a hot strip mill that overcomes the problem of looper instability due to looper inertia without the need for the controller of upstream rollers to have a reduced gain. The inter-stand section of the hot strip mill comprises a pair of upstream rollers driven by a main motor and a looper driven by a looper motor. The method comprises the steps of: calculating a desired speed trim to be applied by the main motor; estimating the inertia of the looper; calculating a torque necessary to overcome the inertia of the looper from the speed trim, the estimated inertia of the looper and a sensitivity calculated from the geometry of the looper; and controlling the main motor to apply the speed trim to the upstream rollers and controlling the looper motor to apply the calculated torque to the looper.

    • The present invention relates to a generator control system that includes a generator, a variable displacement pump, a generator speed sensor, and a generator speed controller. The generator speed sensor generates a measurement output signal that corresponds to the speed of the generator. The generator speed controller generates a control signal that controls the displacement of the displacement pump to limit generator speed surging. The generator speed controller applying default commanded event control gain values to the control signal when a commanded change in the load or speed of the engine or generator occurs, applying uncommantled event control gain values to the control signal in the absence of a commanded change in load or speed of the engine or gen erator, and reducing the uncommanded event control gain values as needed until the magnitude of generator speed surging is less than a threshold value or until a minimum uncommanded event control gain value threshold is reached.
    • 本发明涉及一种发电机控制系统,其包括发电机,可变排量泵,发电机速度传感器和发电机转速控制器。 发电机速度传感器产生对应于发电机速度的测量输出信号。 发电机转速控制器产生一个控制信号,控制位移泵的位移以限制发电机的转速波动。 当发动机或发电机的负载或速度发生命令改变时,发电机转速控制器将默认指令事件控制增益值应用于控制信号,在不存在指令的负载变化的情况下将未连接的事件控制增益值应用于控制信号 或速度,并且根据需要减少不受命令的事件控制增益值,直到发电机速度浪涌的幅度小于阈值或直到达到最小非命令事件控制增益值阈值为止。

    • Multiple designs, systems, methods and processes for controlling a system or plant using an extended active disturbance rejection control (ADRC) based controller are presented. The extended ADRC controller accepts sensor information from the plant. The sensor information is used in conjunction with an extended state observer in combination with a predictor that estimates and predicts the current state of the plant and a co-joined estimate of the system disturbances and system dynamics. The extended state observer estimates and predictions are used in conjunction with a control law that generates an input to the system based in part on the extended state observer estimates and predictions as well as a desired trajectory for the plant to follow.
