Bond graph, transfer function, junction structure, closed loop system
A direct procedure to obtain a bond graph from a state space description or transfer function of a con troller is presented. This procedure is based on a proposed junction structure and elements R or R-field. The junction structure allows interactions only be tween the state variables and the dissipation field and inputs, between the dissipation field and the co-energy variables, and the output variables are only function of the co-energy variables and the inputs. Simple transfer functions for the controllers using 1-port re sistor are designed. However, complex controllers can also be obtained. Moreover, the closed loop system.
