摘要:
针对常规PID控制在非线性、大惯性系统中存在滞后、精度低等弱点,构建了神经网络与预测算法相结合的控制系统.采用预控算法,充分利用预测控制的滚动优化和反馈校正的特性,采用神经网络建立系统的动态模型作为预测控制器的预测模型,实现了对大滞后系统的自适应控制,具有实时控制和预测性能,有效地提高了控制精度和可靠性,增强了稳定性.现场运行结果表明,在空气净化器系统中使用该方法效果良好,易于推广.
Abstract:
Aiming at the weaknesses of conventional PID control such as hysteresis and low accuracy in nonlinear and large inertial systems, a control system combining neural network and prediction algorithm is constructed. The pre-control algorithm is adopted, which makes full use of the rolling optimization and feedback correction characteristics of predictive control, and uses the neural network to establish the dynamic model of the system as the prediction model of the prediction controller, which realizes the adaptive control of the large lag system, which has real-time control and prediction performance, effectively improves the control accuracy and reliability, and enhances the stability. The field operation results show that the method used in the air purifier system has good effect and is easy to promote.
