Design of Typical Input Signal Generator Based on ARM
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.
