AN937, Implementing a PID Controller Using a PIC18 MCU

چکیده
Continuous processes have been controlled by feedback loops since the late 1700’s. In 1788, James Watt used a flyball governor on his steam engine to regulate its speed. The Taylor Instrument Company implemented the first fully functional Proportional, Integral and Derivative (PID) controller in 1940. Although feedback control has come a long way since James Watt, the basic approach and system elements have not changed. There are several elements within a feedback system; for discussion purposes, we will use a home heating temperature control system as our model in the descriptions below.

In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...
