Time Delay PID Controller    

A reliable time delay PID controller.

Overview

The technology relates to the adding of a small time delay in the inside differential link of PID controller. The differential action work is good under the little time delay circumstances and it becomes the proportional control operating status when the time delay is large.

In transient stage, the process response is fast and voluntarily. In starting stage, it is quick to adjust with maximum ratio control. In case of differential and integral element effect, the proportionality coefficient can automatically reduce in order to keep the system stable.

Primary Application of the Technology

The time delay PID controller could be applied to the control field, e.g. converter, temperature control, electric machine controller, etc.
