摘要

激波控制鼓包 (Shock Control Bump，SCB) 是一种被动式的减小激波阻力的方法。针对近年来提到的可变挠度鼓包，提出具有双程记忆效应的形状记忆合金 (Shape Memory Alloy，SMA) 鼓包，可以通过控制 SMA 鼓包的温度改变其挠度，优化 SCB 的减阻性能。为了达到精确控制挠度的目标，提出了一种基于 Preisach 理论的温度 – 挠度迟滞模型。对鼓包进行基于该模型的 PID 控制，试验结果表明该模型可用于 SMA 鼓包的挠度控制中，4 个目标点的最大相对误差为 5.17%，优于无模型的 PID 控制。

Abstract

The shock control bump (SCB) is a passive method of reducing shock drag. Aiming at the deflection-changing bump mentioned in recent years

a shape memory alloy (SMA) bump with two-way memory effect was proposed

which can change deflection by controlling temperature

optimizing the drag reduction performance of SCB. In order to achieve the goal of precise control of deflection

a temperature–deflection hysteresis model based on Preisach theory was proposed. PID control based on the model was conducted

the experimental results show that the model can be applied to the deflection control of SMA bumps

the maximum relative error of the four target points in the experiment is 5.17%

which is better than the PID control without this model.
