For flow loops in parallel, the relative gains of the flow loops approach one as the number of flow loops increase. For a relatively flat pump head curve, the relative gains also approach one. See the ...

For startup, the cascade control system can be operated with just the lower loop in service (e.g. flow ratio control) until operating conditions are reached. However, a secondary flow loop may cause ...

That means the relationship between the controller output signal versus the control valve flow rate will be changing throughout all the different operational conditions and the loop tuning parameters ...

A novel control scheme is proposed for a three-phase buck-type SWISS rectifier. This control is based on an inner loop power flow programming that provides a well damped behavior of the output filter ...

The input from these sensors can be combined with the measured sound velocity to calculate additional gas properties, which are often important for process control. Some examples are volume flow, ...
