Astlingen - a benchmark for real time control (RTC).

This contribution serves two purposes. (1) It presents an updated version of the Astlingen example developed by the working group 'Integral Real Time Control' of the German Water Association (DWA), which serves as a benchmark example for the setup and evaluation of real time control strategies. As this benchmark is also intended for educational use, it demonstrates a simple RTC algorithm, illustrating the main concepts of RTC of drainage system.
