【Abstract】 The traditional PID controller has structural flaws in the integral process control,a kind of internal feedback particle swarm optimization PID control method is put forward,which solves the problem of controlling the integral process.The integral time-delay systems in superheated steam temperature system is difficult to be controlled,but by using the method brought in this paper,the simulation results of the steam flow temperature control system have non-overshoot,short adjusting time,which shows the rationality and validity of the PID control based on internal feedback PSO.更多还原
