PID Controller source code and hardware
Jump start your embedded control project

Our PID Controller source code (C code) has everything you need to realise efficient optimal control, including bumpless PID with limit handling and setpoint weights in all terms, bumpless low pass and notch filters, auto-tuning, and system identification bump tests. Our code is running in all sorts of systems all over the world, such as wind turbine controllers, motion controllers, and mould temperature controllers.
If you want to implement this software in dirt cheap hardware, Arduino might be suitable for you, and we have prepared a full pack for you (hardware and software).
PID Controller Source Code
We provide the source code for industrial PID Controllers, code in ANSI C/C++. typically, this code is used in embedded chips, Arduino, and high-end PLCs. The source code includes all advanced control features used in modern PID Controllers, and more:- Bumpless automatic/manual switching
- Differential Action filtering
- Setpoint Weighting (preventing overshoot)
- Per-programmed bump tests for PID tuning
- Logging of data, for PID tuning with the PID Tuner, and for monitoring
- Self-tuning algorithm
- Second order filters that allows you to create any type of filter, like notch filters, lead lag, low pass. Comes with bumpless initialisation
Customer reviews
” This PID Controller source code with self-tuning algorithms and filters included, continues to work extremely well. We could not be more pleased with the results! ”CEO J-Systems Inc, Lombard, USA.
” We have successfully applied the PID Controller source code in an embedded mould temperature controller. Using the PID Tuner software of DotX we tuned the PID settings to obtain fast temperature control with minimal overshoot. ”
H. van Hulsen, Control Engineer at Small Processor Systems B.V., the Netherlands
