摘　　要：为解决现有信号发生器在单周期信号触发操作上的不便及不满足控制类系统性能分析的教学需求问题,提出了一种能够单周期触发的典型输入信号发生器。该信号发生器以ARM微控制器为核心,可模拟生成阶跃信号、斜波信号、抛物波信号和脉冲信号这4种典型的控制类输入信号,实现了单周期内波形、周期和幅值的调节。通过实验平台测试验证了该信号发生器的设计性能。To solve the inconvenience of existing signal generators in single-cycle signal triggering operations and the unmet educational needs for performance analysis of control systems,a typical input signal generator capable of single-cycle triggering is proposed.The signal generator,with the ARM microcontroller at its core,can simulate and generate four typical control input signals:step signal,ramp signal,parabolic signal,and pulse signal.It has achieved the adjustment of waveform,cycle,and amplitude within a single cycle.The design performance of this signal generator has been verified through testing on an experimental platform.
