摘要: 根据硝普钠降低血压的二阶ARMAX模型,本文推导了仅需计算一个加权参数的极点配 置的显式自校正控制算法.该算法保证了在被控对象有未知时滞、时变、非最小相垃等恶劣情 况下,控制器工作的稳定性和渐近特性.经计算机仿真和利用TP-801单板机控制狗降血压 过程的实验,其结果表明该算法的有效性.Abstract: Based On a second order ARMAX model that sodium nitreprusside decreases blood pressure, an algorithm for the explicit self-tuning controller with pole assignment by calculating only one weight parameter is developed. It maintains the asympotic property and stability of the controller, even when the system is time-varvinq, non-minimum phase, or with unknown time delay. Simulation results and experiments on dog's blood pressure using a TP-801 single board computer show that the controller developed is effective.
