摘要
设计了一种基于自抗扰控制器的控制仪表．它采用ATmega128单片机作为主控制芯片，用8位数码管实现了测量值与设定值的显示，能够采集和输出4-20mA、0～10V等模拟信号，并可以用按键对控制算法参数进行设置．针对FESTO水位对象进行了控制实验，控制器运行稳定，并表现出良好的控制品质．
A control instrument based on the active disturbance rejection controller （ADRC） is designed in this paper. An ATmega128 microcontroller is used as the main control chip, and an 8-bit LED displays the measurement and setpoint values. It is used to collect and output 4-20mA, 0- 10V analog signals, and uses keys to set parameters of the control algorithm. An experiment on a water-level system is done and the results indicate that the controller runs stably and shows good control quality.
