The problem of determining parameters numerical values of the algorithm for the functioning of digital microcontroller implementing proportional-integral-differential control law is considered. The aim of the work is to obtain calculation formulas and methods for parametric synthesis of a control algorithm that en sures the fulfillment of specified requirements for accuracy, speed and quality of control process. To solve this problem, in addition to analytical description of control system, a graphical method is used to construct the desired logarithmic amplitude-frequency response. The analytical and graphical model used is adapted to the features of discrete representation of signals and the functioning of digital control system elements. The experimental part of the work shows an example of calculating the parameters of digital microcontroller control algorithm.
Key words: : proportional-integral-differential law of control, parametric synthesis, digital microcontrol ler, control algorithm, parameters of PID controller, analytical and graphical model of control system.
