摘要
重点研究数字PID控制算法用于信号发生器的功率控制,利用PID先进的控制算法,提高信号发生器输出功率的稳定性和可靠性。在深入分析了增量式数字PID算法流程的基础上,给出了信号发生器功率控制框图模型,利用Matlab从理论上进行了可行性仿真,并从实际硬件电路验证了增量式PID控制算法在跟踪和稳定信号发生器输出功率的过程是一种闭环式的控制过程,实现简单,控制效果良好而且不易振荡。
The paper researches power control of digital PID applied in signal generator, by using advances PID, the stability of signal generator output power is improved. On basis of deeply analysing incremental digital PID,the scheme model of signal generator is proposed,the feasibility simulation using Matlab is given. Practrical hardware circuit verified the incremental PID has closed- loop control process in tracking signal generator output power,it has good results.
