摘要:
对大功率磁控管控制系统进行仿真是稳定磁控管微波功率输出和系统控制器设计的关键所在. 首先,利用实验测量的数据和最小二乘法,在Simulink中建立10 kW磁控管的数学模型,然后进行PID控制器设计. 在控制系统仿真过程中,控制输入量为设定功率所对应的期望输出电流值,反馈量为磁控管的阳极电流,利用Ziegler-Nichols方法对PID控制器参数进行整定. 最终,仿真系统的功率输出达到期望的稳定值,将仿真所得与长时间实践所得进行比较,发现二者的差距甚小. 由于仿真得到的控制器性能稳定且设计过程简便,故能够很好的应用于实际的微波输出控制系统中.
Abstract:
Simulation is the key to stabilize the magnetron microwave power output and design system controller in the magnetron control system of high power. Firstly, the mathematical model of 10 kW magnetron was established by using Simulink/Matlab software based on the experimental data and least-squares method. Then, the proportion integration differentiation (PID) controller for magnetron control system of high power was designed. In the simulation process, we set the controller’s input as the expected current value of the setting power and set the feedback signal as the anode current of magnetron, and adjusted the PID parameters by the Ziegler-Nichols method. Finally, the output power of simulation system reaches the expected value. There is little difference in results between the long-term practice and the simulation. The PID controller can be properly applied into actual microwave output control system with the steady performance and simple design process.
