Control in Bond graph

Post by learnbg » Thu Mar 04, 2010 5:40 pm


I wanted to control the interior temperature of a room. Thus i put an effort sensor to send an information to the source so that the temperature is controled. My question : how to make to precede the sensor by an arrow ? like bellow :

The bond graph 0 and 1 junctions each have a signal output as well (the common effort and the common flow) that you can use in a block diagram directly. If you would like to use an effort sensor, it is meant to be placed between two bond graph elements (in a bond to measure the effort of the bond); it has two power ports and one signal output port.

If you need an effort sensor with just one power port and signal output port, a nice exercise would be to change the Se element into a De element that does just that: it has a power input and generates a fixed flow out of 0.
