IMC-PID: A Control Algorithm for PID Parameter Calculation Based on Internal Model Control Principles

IMC-PID employs internal model control principles to calculate and optimize PID parameters. As an advanced control algorithm, IMC-PID integrates the theoretical framework of internal model control with the practical advantages of PID control, enabling more precise system parameter tuning. The implementation typically involves creating a process model and designing an IMC controller, which is then converted to PID form using specific transformation rules. Through IMC-PID implementation, system control performance can be significantly enhanced, achieving faster response times and improved stability. Although the IMC-PID calculation process is relatively complex, it comprehensively accounts for system dynamic characteristics, resulting in superior control performance. The algorithm typically involves mathematical formulations for calculating proportional, integral, and derivative gains based on process model parameters and desired closed-loop response specifications. Consequently, IMC-PID represents a highly valuable control methodology that finds wide application in various industrial process control systems, particularly in processes requiring robust performance and precise tuning.
