    Simulink linking blocks

    Good day people I have recently started to make random models in Simulink. I have made a model and I am almost done with it, but I can't get my hydraulic torque linked with my electric torque. I guess it's a stupid question. Does anyone know how to solve this? In the last part, I factored...

    Hi At my previous company, they didn’t use a master and slave option. They compared the speed of each cylinder. The cylinder with the highest speed will be reduced so that the other cylinders can catch up. I tried to understand the control loop but I was missing integrators and knowledge to...

    Combining a loadsensing pump with a fixed displacement pump

    Good Afternoon people My question is is it possible to combine two pump-sets with a configuration one variable displacement pump with a load sense control and a fix-displacement pump. These pumps are connected to a system with two users. One user needs 40 l/min and the other user needs 20...
