The basic configuration of feedback control is shown in FIG. The command value (target value) ei and the output value (control value) eo of the controlled object 2 are compared and amplified by the control amplifier 1, and the input of the controlled object 2 is controlled by the output (operated value) ec, and the output value eo is set as the command.

FIG. 2 shows a case of speed control of an electric motor as an example of feedback control. This speed control will be explained below as an example. The purpose of this speed control system is to control the speed no of the electric motor 4, and the command value is given by the speed command value ni. The speed command value ni and the speed no detected by the speed detector 5 are compared and amplified by the control amplifier 1, and its output ec is input to the power amplifier 3. The power amplifier 3 performs power amplification in order to cause a current i corresponding to the input ec to flow through the motor 4. An electric motor generates a torque proportional to the current, and the speed increases or decreases according to this torque, resulting in a speed deviation (ni
-no) is controlled to be small.

Figure 3 shows a simple proportional amplifier that can be used as a control amplifier. 6 is a subtracter and 7 is an amplifier for input.
Amplify by Kp times. The deviation between the command value ni and the detected output value no is obtained by the subtracter 6, and is simply
It just amplifies it by Kp times. In order for the output ec of control amplifier 1 to have a certain value, there must be a deviation, and if the motor is generating torque, the speed will differ from the command value even in a steady state where the speed command and load torque are constant. It will have a deviation (steady deviation).

However, when a proportional-integral amplifier is used, as shown in FIG. 5, a so-called overshoot occurs in which the speed exceeds the command value once in response to a change in the speed command value ni. In feedback control, there is always a control delay, and the amount integrated during this delay (proportional to the area of A shown in the figure) and the amount negatively integrated at the overshot part (proportional to the area of B shown in the figure) (proportional to) must be equal.

Overshoot of the speed no can be prevented by adjusting the constants K A and ω A so that the area of this hatched portion and the amount integrated by the control delay (area of A in the figure) are equal.

Recently, on the other hand, attempts have been made to digitally control and amplify these signals using microcomputers and the like to improve accuracy. Digital integration can perform error-free integration, and in the case of a proportional-integral amplifier, steady-state deviation can be completely eliminated. However, when differential calculation is performed with overshoot prevention compensation added, the amount of differentiation becomes infinitely small as the steady state approaches, and digital calculation has no choice but to abort the calculation. Therefore, in proportional-integral amplification with overshoot prevention compensation, steady-state deviation cannot be completely eliminated even if digital calculations are performed. There was a desire to develop a control amplifier suitable for digitalization in order to achieve high performance and high precision control.
