PID Controller Design Using Genetic Algorithm (GA)

A PID controller was designed using Genetic Algorithm (GA). Through comprehensive simulations and testing, the controller's effectiveness and superior performance have been validated. The simulation results indicate that this controller exhibits excellent stability and rapid response capabilities, enabling precise control of system operations. Furthermore, the controller demonstrates strong robustness, adapting effectively to varying working conditions and parameter changes. The implementation leverages GA's optimization capabilities to evolve optimal PID parameters (Kp, Ki, Kd) through fitness evaluation, selection, crossover, and mutation operations. By further optimizing and refining the controller through additional generations of genetic evolution or modified fitness functions, system performance and stability can be enhanced. Key implementation aspects include population initialization with potential PID parameters, fitness calculation based on control performance metrics (e.g., ISE, IAE), and genetic operators to converge toward optimal solutions.
