摘　　要：为了实现反作用飞轮速度的高精度和高可靠控制,围绕基于线性霍尔传感器的飞轮控制系统展开了研究.介绍了线性霍尔传感器速度检测原理,提出了一种实时的速度和位置解算算法.该算法首先对霍尔信号在线标校;通过间接计算反正弦的方式,提高位置解算效率,从而实现位置的实时解算;通过选取最优霍尔信号曲线,提高位置计算精度.实验结果表明:在高转速时,飞轮速度控制精度优于1 r/min;在低速时,速度控制精度优于1.5 r/min,零转速控制精度达到了0.3 r/min.In order to achieve high-precision and high-reliability control of the reaction flywheel speed,The research on the flywheel control system based on the linear Hall sensor is carried out.The principle of linear Hall sensor speed detection is introduced.A real-time velocity and position calculation algorithm is proposed.The algorithm first performs online calibration of the Hall signal;by indirectly calculating the arc sine,the efficiency of position calculation is improved,so as to realize the real-time calculation of position;By selecting the optimal Hall signal curve,the accuracy of position calculation is improved.Experimental results show that at high speed,the flywheel speed control accuracy is better than 1 r/min;at low speed,the speed control accuracy is better than 1.5 r/min,and the zero speed control accuracy reaches 0.3 r/min.
