摘要
基于激素分泌调节的超短反馈机制,设计了一种智能超短反馈控制器(NUC),并给出了其具体控制算法。该NUC包括传统控制单元、超短反馈单元、信号运算单元和信号输出单元等。NUC的控制输出信号,首先经超短反馈单元传输至信号运算单元,然后信号运算单元按照激素调节分泌规律进行处理。最后,信号运算单元处理后的信号与传统控制单元的输出信号,经信号输出单元进行合并运算和输出,从而构成一种非线性控制算法。仿真结果表明,相对传统PID控制,NUC具有较好的稳定性、鲁棒性和抗干扰能力。
Based on the ultra - short feedback of neuroendocrine system, the paper presents a novel intelligent controller with ultra -short feedback （NUC） and provides its control algorithm. The NUC is composed of a conventional control unit （CCU） , an ultra- short feedback unit （UFU） , a signal process unit （SPU） and a signal output unit （SOU）. The output of NUC is first fed back to the UFU and processed there. Next, the processed signal is transmitted to SPU and calculated according to the hormone modulation law. Finally, the output of SPU and that of CCU both are transmittted to the SOU, where they are dealt with and out put. Thus, a nonliear control algorithm is formed. Simulation results demonstrate that the stability, the ability of noise suppression and robust of NUC are better than those of the conventional PID controller.
