PI Temperature Control Integrator

 

Proportional-integral response for control systems can be generated by a simple analog circuit. Feedback components R2, C2, & C1 together with input resistor R1 control the frequency response of U1. R3 is added to the circuit to provide feedback in a DC analysis and it is not necessary in an actual circuit. For stability, the control loop dominant pole should be formed by this integrator.

Graeme Double Integrator

By placing the poles of two Tee networks (R1, C1, R2 & C2, R3, C3) at the same frequency, U1 performs double integration of its  input signal Vin. The gain of the circuit is dependent on the values of the R & C values. For additional information, see “Applications of Operational Amplifiers- Third- generation Techniques” by Jerald G. Graeme. In the absence of system feedback, R4 is used to close the loop to establish a DC operating point. It is not necessary in actual operation. (Circuit is created by Neil P. Albaugh,  TI – Tucson)
