摘要
采用TI公司的浮点式TMS320VC33 DSP开发系统,用于静电悬浮转子微陀螺的悬浮控制试验。介绍了微陀螺控制系统的硬件结构和软件设计,搭建了Simulink控制系统模型,并利用劳斯判据在理论上推导了PID参数的选取范围。研究了不同频率的正弦激励信号对系统输出的影响;计算了其主要电气参数,并设计了微陀螺的开环、闭环和刚度性能指标。最后,给出了静电悬浮转子微陀螺系统初步的悬浮控制结果。
TI＇s floating-point type TMS320VC33 DSP development system is used for the suspending experiment of the electrostatically levitated micro-gyroscope.The hardware and software designing are described.A simulink model is set up,the selection of PID parameters is derived theoretically.The influence of different frequency sinusoidal excitation signal for the output of the system is discussed,and the electrostatical parameters are calculated.The performance of the micro-gyroscope about open-loop,closed-loop and stiffness are designed.Finally,the results of the initial suspension are given out.
