摘要
为了满足新型弹、箭系统的性能要求,惯性平台系统的技术跨度越来越大,研制周期却越来越短,因此研制难度大大增加。惯性平台系统构造复杂,涵盖了机械、力学、电子、控制、材料等多门学科,为了尽早发现方案性的技术问题,减少技术风险,迫切需要开展惯性平台仿真技术的研究。以某四轴平台为例,建立了包括平台系统和惯性仪表运动学及动力学模型、电机及传感器模型、以及调平/锁定回路等在内的整个惯性平台系统的数学模型,并利用Matlab搭建了一个完整的仿真惯性平台,对该平台的空间稳定功能以及台体转位、调平锁定等核心功能进行了数学仿真,并采用Vega软件进行了三维动画输出,仿真结果与原型平台的实际输出相符。
The development of new-style inertial platforms becomes increasingly difficult due to its＇ complexity and short development period. Inertial platform system is quite complicated, covering many disciplines such as mechanics, electronics, control and material science, etc. Consequently, in order to find scheme error in time and decrease technology risk, inertial platform simulation technology is urgently needed. In this paper, the whole math model of some 4-axes inertial platform is established, including kinematics and dynamics model of the platform system and its＇ inertial instruments, the output model of motors and sensors, control loops and etc. Based on it, an entire simulation inertial platform is accomplished. The core functions are simulated, including space stable, rotation, level and locking. The result is output in the form of three-dimensional animation by adopting Vega and the simulation result accords with the real output of the platform.
