Optimization of main steam temperature control system based on improved electromagnetism-like mechanism algorithm

In this paper, according to a thoughtful study of electromagnetism-like mechanism algorithm, proposing a method of parameters optimization for PID controller based on the improved electromagnetismlike mechanism algorithm. Aiming at these problems that the initial population in the original algorithm is not uniform, the local search efficiency is low, and the resultant force calculation is complex. The algorithm is improved, and it has advantages with fast searching speed and simple principles, which can effectively improve the stability of the control system. Finally, through the simulation of the main steam temperature control system, which is a typical large inertia and large delay thermal object. The PID controller is difficult to meet the performance requirements of the object, the simulation testifies the feasibility and reliability of the algorithm and prominently improves the controlling quality.
