A PID tuning guide with almost no math. But very important thing to consider when making an system identification test indeed.

I like that it has no math or equations, only practical tips.

Not sure I can (legal reasons?), but suffice to say thay feed multiple stations with multiple relatively large machines (+10MW). In some cases they have daisy-chained basins, so there are also level inner-loops to be tuned. So the approach

For me the most complicated part when doing manually was the delay, because the water from the intake gates do not reach the headponds inmediatly. What I like is that the tool considers the delay in the tuning.

I have used this tool to tune the water level PIDs of several hydroelectric substations. I passed from spending days with manual fine tuning to a couple of hours of a simple experiment and tuning with this tool.

Thers is this tool whole algorithms were originally implemented in C++ to use in industrial applications. But was easily ported to the web to create a PWA that now anybody can use. This would have not been possible before. Check it out: ht

It is athough question, given that C++ is multi paradigm and recently changing a lot (last 10 years). There is: * Classic C++ (before C++11) * Modern C++ (after C++11) * Object oriented C++ * Functional C++ * Metaprogramming (Template) C++

A system can have any number of states (variables that store energy). The output of that system is a combination of those states. Some states can have slow dynamics, while other states have fast dynamics. Is is possible for a system to have

Just use a simple linear non-causal filter, i.e. low pass filter forward in time and then backwards in time. Do this for any desired bandwidth and iterate as many times as you want. No need for neural networks in here.

Industrial software, at the SCADA level. Basically "industrial IOT" (aka indistry 4.0). Moving data from one place to another. Historial data, events, alarms, reports, human-machine interfaces (aka GUIs). Mostly C and C++. C++ rea

WrDesigner author here. I started the QtDesigner-like tool for Wt because I had a project where I needed to expose some existing C++ code on to the web. In the end I never used it. As I learnt web technologies, I found much flecible and eas

Create a whatsapp group and add one person, then inmediatly kick out that person from the group. Then you have a group for just yourself. Call it "links" group. Use this group to paste links. On the desktop use https://
