摘要:
提出了一种基于多步预测的PID型神经网络控制方案 ,其控制机理类似于位置递推式PID控制 ,但所产生的控制量是误差信号的比例、积分和微分量的一种非线性组合 ,可以有效地克服常规PID控制存在的快速性和超调的矛盾。通过利用多步预测误差对PID型神经网络控制器进行训练 ,可以弥补单步预测存在的控制信号波动较大的缺陷。仿真实验表明 ,基于多步预测的PID型神经网络控制系统能有效抑制随机干扰 ,具有较强的适应性和鲁棒性。
Abstract:
A mult-i step predict ion is presented in this paper based on PID-like neural netw ork cont rol scheme similar to the position successive PID in cont rolling mechanism. T he new cont roller can not only carry out the operat ions of proport ion, integral and different ial of error, but also adapt ively adjust PID parameters. The cont rol signal produced by this controller is a nonlinear combinat ion of the values of proportion, integral and derivat ive of errors. Hence, the cont radict ion of fast response and overshoot , which exists in the conventional PID regulator, can be effect ively solved. The new PID-like neural network cont roller is t rained by a performance index based on mult-i step predictive errors. This can effect ively overcome the shortcoming that cont rol signal severely fluctuates accompanied w ith one-step predict ion. Simulation result s prove that this new mult-i step prediction based on PID-like neural netw ork control system can effectively at tenuate random noise interference and is more robust and adaptive.
