Summary:In this article, the design of a high precision, low-cost PID acquisition system and the design of PID control system are shown. The PID acquisition system consists of a measurement unit connected to a Raspberry Pi 4, where temperature data is stored and plotted. The Ziegler-Nichols tuning method is used to calculate and tune the PID control system. The PID control system is based on a dual-core microcontroller Raspberry Pi Pico RP2040 using a standard closed-loop PID algorithm. The systems run using Python and MicroPython. This article uses PTC heating element temperature control as an example.
