摘要
以导弹电动舵机为研究对象,阐述了其组成结构和自检原理,在舵机自检BIT的基础上,应用递推最小二乘法(RLS)对舵机参数进行估计,提出了一种选取故障检测阈值的实验方法,通过MATLAB/SIUMULINK仿真验证了该方法的可行性。
Focusing on a kind of missile electromechanical actuator, the structure and self-testing principles are discussed. Actuator parameters are achieved via the recursive least squares （RLS） estimation algorithm based on actuator BIT. And an experimental method for choosing fault detection threshold is advanced, the feasibility of which is validated via simulation launched in MATLAB/Simulink.
