    • Methods and systems for assessing transmitter electronics in an industrial process control system comprise generating a process condition reference equation signal, a process condition approximation equation signal, and an accuracy output signal. The process condition reference equation signal is generated using a process condition reference equation and process control inputs. The process condition approximation equation signal is generated using a process condition approximation equation that approximates the reference equation using the process control inputs, and approximation equation coefficients based on the approximation equation and the process control inputs. The approximation equation signal is compared to the reference equation signal at a control room workstation such that the industrial process control system can be adjusted. In one embodiment, the approximation equation coefficients are adjusted and transmitted to process transmitter electronics over a control network. In another embodiment, a parameter of the industrial process control system, such as a primary element or transmitter, is adjusted.
    • 用于评估工业过程控制系统中的发射器电子器件的方法和系统包括生成过程条件参考方程信号,过程条件近似方程信号和准确度输出信号。 过程条件参考方程信号是使用过程条件参考方程和过程控制输入产生的。 处理条件近似方程信号使用近似使用过程控制输入的参考方程的过程条件近似方程以及基于近似方程和过程控制输入的近似方程系数来生成。 近似方程信号在控制室工作站与参考方程信号进行比较,从而可以调整工业过程控制系统。 在一个实施例中,近似方程系数被调整并通过控制网络传输到处理变送器电子器件。 在另一个实施例中,工业过程控制系统的参数,例如主要元件或发射器被调整。

    • A sliding mode control apparatus. When displacing a controlled object to which an urging force is applied by an elastic member from one displacement end to the other displacement end, the control apparatus sets a switching hyperplane and controls the controlled object by using a sliding mode control in such a manner that a state quantity of the controlled object is converged on the switching hyperplane. In the sliding mode control, the control apparatus switches an operation mode for controlling the controlled object when the controlled object passes an operation switching point. The control apparatus detects disturbance in the sliding mode control and a change with time of the elastic member, and changes the operation switching point in accordance with both of the detected disturbance and the detected change with time.
    • 滑动模式控制装置。 当通过弹性构件从一个位移端向另一位移端移动施加施力的受控对象时,控制装置设置切换超平面并且通过使用滑动模式控制来控制受控对象, 受控对象的状态量会聚在切换超平面上。 在滑动模式控制中,控制装置在受控对象通过操作切换点时切换用于控制受控对象的动作模式。 控制装置检测滑动模式控制中的干扰和弹性构件的随时间的变化,并且根据检测到的扰动和检测到的变化随时间而改变操作切换点。

    • A method of sliding mode control for realizing a control system which exhibits strong robustness and excellent control stability. A processor of a digital servo circuit of a servo control system includes a position loop that effects proportional control, a speed loop that effects proportional-plus-integral control to calculate a torque instruction, and a current loop that responds to the torque instruction. The processor calculates a position deviation (x1), the differential (x2) of the position deviation, the integral (x3) of the differential of position deviation, and the integral (x4) of the position deviation (100 to 103) based upon an instructed position (Υr), the actual position (Υ) and actual speed (Υ), and further calculates a switching surface (s = x2 + C.x1 + K.x3 + K.Kp.x4) in the sliding mode control and a discrimination reference value (Kp.x1 + x2). The processor further calculates switching quantities ((τ', τ') that enable the characteristics of the control system to be converged on the switching surface depending on the switching surface, position deviation and discrimination reference value of positive or negative sign, and the motor is operated according to a torque instruction (τ = τ' + τ') obtained by adding them up together. The robust control system controlled by the sliding mode does not permit the characteristics to change even when the motor inertia undergoes a change.
