The pump house constant pressure fuzzy self-tuning PID control system simulation

摘要

Constant pressure water supply for the pumping station complex large time delay system, traditional PID control is difficult to ensure that any working condition always have a good control performance and fast response. These papers presents speed control system of constant pressure pump unit using fuzzy self-tuning PID control strategy, in order to achieve real-time tuning of PID parameters, and design a fuzzy self-tuning PID controller. Constant parameters of the actual pumping station based on a model in Matlab / Simulink simulation model built in the simulation results show that the fuzzy self-tuning PID controller with the output response than the traditional PID fast adjustment time is short, no overshoot, steady-state, high precision, right parameters has strong robustness, etc., can be a good solution to a complex pump-delay system problems.
