Adjusting PID controller control parameters

摘要

The method involves adjusting a PID regulator (3) with control parameters P,I and D for e.g. a damped, harmonic oscillator (5) with characteristic system parameters k for damping, i for generalised mass and d for a generalised force as controls in a closed control loop with negative feedback. The parameters P,I and D are set as follows: P=D=m/torr and I=d/torr. Torr is the aperiodic transient time of the control parameter of the closed loop. The arrangement for adjusting the parameters may include one or two electronic computers (1) and/or a control member and/or sensor elements. With two computers, they may be combined into one.
