惯导平台稳定回路的高精度控制方法对比分析

摘要

Platform inertial navigation with its unique advantages has been widely used in engineering fields. Accuracy is an important indicator of the inertial navigation system, and the accuracy of the platform inertial system depends largely on the control method of the stabilization loop. The paper takes a certain type of inertial platform stability loop as an example to introduce several common high precision platform stabilization loop control technologies in recent years: PID control, fuzzy PID control, multi-loop control and sliding mode variable structure control, then the feasibility and advantages of four control strategies are analyzed by simulation. It can give great guidance for the research of stabilization loop.%平台式惯性导航凭借其独特的优势被广泛运用于工程领域中.导航精度是衡量惯性导航系统性能优劣的重要指标,而平台惯性导航系统的精度绝大程度上取决于稳定回路的控制方法.以某型号的惯性平台稳定回路为例,介绍了几种常见的高精度平台稳定回路控制技术:PID控制、模糊PID控制、多环控制和滑模变结构控制,并通过仿真对比分析了4种控制策略的可行性与优缺点,对研究稳定回路的高精度控制具有积极的指导意义.
