【 摘 要 】

The paper analyzes the main steam temperature of the boiler with multi-model switching control based on the PID control system. According to the calculation result of the multi-model switching index, when the boiler load changes, the switcher will switch the controlled object of the boiler to the closest corresponding control model under the typical load. Moreover, the function of the leading zone and the function of the inertia zone of the PID control system are integrated into an equivalent first-order inertia plus pure lag function. Comparing these two methods, it is concluded that the control system with the first-order inertia plus pure lag function has a better control effect.
