摘　　要：探讨了基于DSP的功率放大器功率数字控制方法，分析了传统控制算法如定步长算法、比例算法和PID算法在实现射频功率的数字自适应控制上的缺点和不足，在传统算法基础上进行改良，改善了射频功率控制的过冲现象，减小了控制调节时间，实现了输出功率的稳定。In this paper, RF-power digital control methods based on DSP were investigated. The disadvantages of traditional algorithms such as fixed-step algorithm, proportional algorithm, PID algorithm used in R.F-Power digital self-adaptive control were analyzed . Based on these traditional algorithms, a improved algorithm was obtained, which improved overswing phenomenon, decreased the control adjust time, realized the steady of output power.
