| Research Abstract |
In multivariable control systems, controlled variables interact with each other in general. In this case, compensation for a control loop exerts harmful influence upon other control loop through the interaction. If we could take away this interaction by some ways for a complete one to one corresponds between the manipulated variable and the controlled variables, then the design of control systems results in the individual compensation of the single loop control.
A cross controller was used for removing the interaction thus far mainly, but it was complicated and the controller was high-order. On the other hand, the precompensator by the inverse Nyquist array method was also used for non-interaction of the controlled variable. However, it is difficult to remove the interaction of the controlled system, which has very strong interaction, when the precompensator is used only one.
This research proposed the series and/or parallel connections of the precompensators for noninteracting PID control, and then the precompensators are applied to the control of the fluid temperature and liquid level interacting plant to confirm the effectiveness.
