Time-delay Proportional-Integral-Derivative (PID) Controller

Summary: The invention proposes the adding ay to the insidof a small time-dele differential link of a PID controller. The differential action efficiency is satisfactory when the time delay is little. In case the time delay is large, the differential action work will switch to the proportional control operating status. The delay PID automatically provides a fast control at the transient state. In the beginning, it gives the highest proportional control to speed up the performance, and reduces it to maintain stability once the derivative or integral action is on.

Technology Application: •For application in converters, temperature controls, and electric machine controllers etc.
