摘要
本研究设计了一种新的自校正控制器——最小偏差超前控制器(MDAC)。MDAC在大于或等于纯时延的某一时刻使实际输出值与设定值的方差为最小。可用于控制带有未知或变化时延的Ⅰ、Ⅱ型非最小相位系统,具有快速、平滑、稳定的特点。用于控制家兔平均动脉压,可在95.8％时间内将其稳定于设定值±0.67kPa误差带内。
An adaptive control algorithm-the minimum deviation advance controller (MDAC) ispresented. MDAC minimizes the variance between real output and set point at a time advance which is equal to or greater than the dead time. It can control type Ⅰ and type Ⅱ non-minimum-phase system with unknown or varying dead times fast,smoothly and steadily.MDAC maintained the mean arterial blood pressure of rabbits within ± 0.67kPa of the desired value at 95.8% of the time despite the presence of disturbance.
