摘　　要：针对大负载、高精度、超低速的用于卫星飞行模拟的实验转台,在进行这种转台的机械结构和传动系统的设计基础上,构建了相应的高精度直流伺服控制系统。然后,建立了系统的数学模型,利用基于Lyapunov直接法的鲁棒模型参考自适应控制策略,对系统的速度稳定性进行了研究。通过实时仿真,使系统的跟踪误差渐进收敛。On the basis of designing the mechanical architecture and transmission systems of-an-experimental simulator with high precision, super-low speed and large load for simulating the flight of satellites, the paper constructs its corresponding DC servo control system with high precision, the mathematical model of which is also established. Furthermore it studies its speed stability through using a robust adaptive control scheme based on Lyapunov＇s direct method. The real-time simulation of the system indicates that the scheme accomplishes the global convergence of tracking errors.
