The problem of optimal adjustment of a PID regulator, which is basic algorithm for automatic control systems for thermal plants, remains relevant. A simple and practical method of adjustment the PID regulator, using the transient function of the open control clop in the time domain is offered, convenient for practical use. The optimal graph of the transient function of the open control loop should be a broken straight line with delay. By varying time constants of the integration and differentiation channels of the PID regulator, the graph of the transient function of the open control loop should be straightened, that is converted to a straight line with delay. Variating the proportionality factor of the regulator, the growth rate (slope of the graph) of the transient function should be made 0.52, relative to its delay. Adjusting the PID regulator according to the proposed method guarantees the minimal possible regulation time. The proposed method for adjusting the parameters of a PID regulator is recommended to be used both for the computer simulation of the regulation dynamics and for operating systems of automatic control.
