This is a simple tool for simulating PID controller with configurable parameters in a negative unit feedback loop.
The structure of the PID controller is the parallel structure, cannot be changed for this simulator.
The simulator supports visualizations of impulse response, step response, Bode plots, Nyquist plot, Root-Locus plot.
This tool is developed for educational demonstration purpose, not meant for extremely accurate scientific visualization.
To use the tool, you may just download the installer using the link above and install the application on your computer.
After successful installation, you may just open the installed application and start with the simulation after you fill in the desired plant transfer function.
The variable you use for the transfer function must be the Laplace variable 's'. The rule for filling in your symbolic transfer function follows the rule of sympy.
