为了缩短姿控飞轮控制系统的设计周期和快速验证设计方案的可行性及有效性,在分析姿控飞轮电机本体数学模型的基础上,结合该姿控飞轮控制系统所采用的加速控制、制动控制、换相控制,建立了姿控飞轮控制系统模型。针对姿控飞轮的共性问题:飞轮过零响应问题,以速度模式下的指令响应为例分析了调压调速控制方式与调压调速结合反接制动方式下的飞轮速度、电流、端电压以及力矩响应。分析结果表明:在0.025 Hz的速度指令下,调压调速结合反接制动方式具有更好的过零响应。

To shorten the design period of control system of a satellite attitude control flywheel,and to verify the feasibility and effectiveness of design schemes,a control model based on a mathematics model for flywheels was established combined with acceleration techniques,reversal connection braking control and commutation control for the control system of flywheels. By taking the speed instruction in a speed control mode for an example,the speed responses,currents,terminal voltages and torques were analyzed by the variable voltage speed control method and the variable voltage speed control combined with reversal connection braking method.The results indicate that the latter has better performance than that of the variable voltage speed control method at a speed instruction of 0.025 Hz.
