【摘要】：转速是影响转子式微陀螺性能的关键因素,因此转子式微陀螺必须工作在较高转速下。为缩短转子式微陀螺的启动时间,提出了一种适用于球碟转子式微陀螺的新型驱动系统。该系统以微控制器为核心。首先,微控制器作为正弦脉冲宽度调制信号发生器,产生驱动永磁转子旋转的驱动磁场。其次,利用反电动势检测方法,通过检测转子在空闲驱动线圈中感应的反电动势,判定转子实时位置。之后,运用微控制器中的控制算法,保证转子在加速过程中加速度始终处于安全范围,并在达到设定转速时保证转子恒速运行。利用该控制算法,可以预防系统运行中出现失步现象而导致转子停转。实验结果表明,在自适应快速启动技术支持下,该器件启动速度可以提高36.6%。
[Abstract]:Rotor speed is the key factor to affect the performance of rotor micro gyroscope, so rotor micro gyro must work at higher speed to shorten the starting time of rotor micro gyro. In this paper, a new drive system for spherical disk rotor micro gyroscope is proposed. The microcontroller is the core of the system. Firstly, the micro controller is used as the sinusoidal pulse width modulation signal generator. Second, using the backEMF detection method, by detecting the rotor induction in the idle drive coil back EMF, determine the rotor real time position. The control algorithm in the microcontroller is used to ensure that the acceleration of the rotor is always in the safe range during the acceleration process and the constant speed of the rotor is guaranteed when the speed is set. The experimental results show that, with the support of adaptive fast start technology, the start-up speed of the device can be increased by 36.6%.
