System inversion is a concept that often appears either implicitly or explicitly in the design of control systems (e. g. decoupling, feedback linearization or feedforward control). This paper presents an algorithm for the representation of an inverse

A graphical method to study the zero dynamics of linear time-invariant SISO systems is presented based on bond graph representation and using causality and bicausality manipulations on the bond graph. It is shown that in the construction of the inver

In the robotics field control laws taking into account the nonlinearities caused by the mechanical structure have been proposed, assuming that the drive system is linear. These control laws are well-adapted to the case of electric actuators. Electroh

International audience; Two different algorithms for deriving the inverse system state equations from a bond graph model are presented Their first method is based on the causal path analysis and it leads to the full-order inverse system. The second m

In tracking or position control of an electropneumatic servodrive modelling errors like the leakage mass flow rates and the gravity torque or also the dry friction, constitute a serious constraint when designing a control law. We describe in this pap

This paper deals with two control methods applied to an electropneumatic servodrive: a state-affine control law and a sliding control. The first one replaces a set of linear control by anunique non-linear control law valid for all operating points an

PWM (Pulse width modulated) solenoid valves possess the advantages of low cost, high flow rate gain, and simple structure. However, the use of a PWM solenoid valve causes both discontinuity and nonlinearity of the flow rate; this results in difficult

The aim of this paper is to analyze the structural properties of an electropneumatic servovalve/long pneumatic actuator assembly by using a bond graph representation. This analysis is based on a linearized distributed model which is able to take into

In fluid power systems, lines or pipes can have a predominant effect on dynamics. Although many studies have been carried out on hydraulic pipe modeling, there are only a few existing approaches for such problems in pneumatics. This paper proposes an
