چکیده
Zusammenfassung Der Beitrag beschäftigt sich mit der Parametrierung der nichtlinearen Zustandsregelung durch Interconnection and Damping Assignment Passivity Based Control (IDA-PBC). Die Struktur der geregelten Strecke als Port-Hamilton (PH) System ist physikalisch motiviert und beruht auf der Speicherung, dem Austausch und der Dissipation von Energie. Die Wirkung der Entwurfsparameter in den vorzugebenden Strukturund Dämpfungsmatrizen sowie der Energiefunktion auf das Zeitverhalten ist jedoch in der Regel undurchsichtig. Die BetrachtungderLinearisierungdesgeregeltennichtlinearenSystems in Abhängigkeit der Entwurfsparameter bietet die Möglichkeit, wenigstens lokal gewünschtes Zeitverhalten systematisch im Regelungsentwurf zu berücksichtigen. Summary This contribution deals with the parametrization of nonlinear state feedback control by Interconnection and Damping Assignment Passivity Based Control (IDA-PBC). The Port Hamiltonian (PH) structure of the controlled system is physically motivated and incorporates the idea of storage, exchange and dissipation of energy. However, in general the effect of the design parameters in the interconnection and damping matrices and the closed loop energy on the time behavior is intransparent. Considering the linearization of the nonlinear closed loop systemwith respect to the design parameters is a systematic possibility to include at least locally desired time behavior in the design procedure.

Local linear dynamics assignment in IDA-PBC
In this paper, the technique of local linear dynamics assignment is presented, which complements the powerful Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) methodology. In IDA-PBC, nonlinear state feedback controllers are designed by matching the system’s dynamics with a desired Port-Hamiltonian (PH) state representation. The latter consists of an energy function, whi...
متن کاملSimultaneous Interconnection and Damping Assignment Passivity-based Control of Mechanical Systems Using Generalized Forces
To extend the realm of application of the well known controller design technique of interconnection and damping assignment passivity–based control (IDA–PBC) of mechanical systems two modifications to the standard method are presented in this article. First, similarly to [1], it is proposed to avoid the splitting of the control action into energy–shaping and damping injection terms, but instead ...

In this paper we compare the two well known nonlinear control design techniques Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) and Immersion and Invariance (I&I) at the example of the so-called Acrobot underactuated mechanical system. The immersion and matching equations in both approaches have a similar structure which is exploited to derive equivalent control laws, e...
متن کاملPhysical Damping in IDA-PBC Controlled Underactuated Mechanical Systems
Energy shaping and passivity-based control designs have proven to be effective in solving control problems for underactuated mechanical systems. In recent works, Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) has been successfully applied to open loop conservative models, i.e. with no physical damping (e.g., friction) present. In a number of cases, in particular when I...
متن کاملA simplified IDA-PBC design for underactuated mechanical systems with applications
We develop a method to simplify the partial differential equations (PDEs) associated to the potential energy for interconnection and damping assignment passivity based control (IDA-PBC) of a class of underactuated mechanical systems (UMSs). Solving the PDEs, also called the matching equations, is the main difficulty in the construction and application of the IDA-PBC. We propose a simplification...
