Low Cost PID Controller for Student Digital Control Laboratory Based on Arduino or STM32 Modules

In the teaching process, it is important that students do not carry out exercises only by computer simulations, but also they research in real time. times of distance learning during COVID-19 pandemic, would be necessary to find a solution so can perform such individually at home. Therefore, has become develop cheap and simple modules digital controllers along with analog objects adjustable order time constants. This paper describes low-cost proportional–integral–derivative (PID) controller for control techniques The PID based on widely available microcontroller Arduino or STM32. advantage this algorithm calculated every constant period Both solutions presented have been successfully tested practice remote pandemic.
