稳定平台电机负载仿真模型的建立及验证

稳定平台可以很好地隔离载机飞行过程中的角扰动，而控制系统的设计对其隔离性能的实现至关重要。针对在使用Simulink仿真时，数学模型中电机特性以及负载的影响难以确定的问题，通过实验数据对模型校准，以及设计的3种不同模拟负载进行了试验验证，从而得到了精确的仿真模型。研究结果表明，该模型能够真实反应电机及负载的特性，有利于稳定平台控制系统的仿真设计，保证了稳定平台的Jl~,N交付。

Design and validate of electromotor loading model on stabilization platform

The stabilized platform can be used to isolate carrier aircraft angle disturbance, so the design of stabilizahon plattorm control sys- tem is very important to realize the performance of platform. In order to solve the problems that the mathematical model of motor characteris- tics and the loading is difficult to determine the influence of the problem by using Simulink toolbox, through the experimental data, the model calibration, and the design of three different load simulation were tested, thus the accurate simulation model was obtained. Research results show that the model can true respond motor and load characteristics, and it is favorable for the simulation design of the stabized platform con- trol system, guarantees the smooth delivery of stabilized platform.
