Unendlich-dimensionale Systeme

Infinite-dimensional systems are characterized by states, which are elements of an infinite-dimensional state space. An important subclass are distributed-parameter systems, with their dynamics depending both on space and time. The research group „Infinite-dimensional Systems“ develops new methods for the feedforward and feedback control as well as for the fault diagnosis of distributed-parameter systems. Important application areas range from flexible structures, chemical reactors to electro-chemical energy storage systems.

Backstepping control of coupled PDE and PDE-ODE systems

In this research project new methods are derived for extending the backstepping approach to coupled PDE and PDE-ODE systems. This class of distributed-parameter systems (DPS) arise frequently in applications. Examples are chemical reactors described by their temperature and concentration profiles, DPS with dynamic boundary conditions, with finite-dimensional actuator and sensor dynamics or with input and output delays. The work in this project focuses on new backstepping-based design procedures for observer-based compensators.

Backstepping-based output regulation for distributed-parameter systems

Besides the pure stabilization an additional basic property of a controller is to achieve the asymptotic tracking of online prescribed reference inputs in the presence of disturbances. If these exogenous signals are describable by a signal model, then the output regulation theory provides a systematic framework for the controller design. In this research project the backstepping approach for boundary controlled distributed-parameter systems is combined with results from output regulation theory. This yields new systematic procedures to determine output feedback regulators for distributed-parameter systems.

Fault diagnosis and fault tolerant control for distributed-parameter systems

Due to the increasing complexity of technical systems the detection of faults and their consideration in the controller design becomes more and more important in order to assure the safety of various technical processes. Though this problem has been thoroughly investigated for finite-dimensional systems only a few results exist for distributed-parameter systems. In this research project new methods for the fault detection in infinite-dimensions are derived. In order to take faults in the closed-loop system into account new approaches are developed for fault tolerant control.

Structure preserving approximation of distributed-parameter systems

Classical order reduction methods use an FE-model of the underlying distributed-parameter system. This has the disadvantage that a very high order FE-model is needed for an accurate system description, which leads to a high numerical effort in the order reduction. In this research project new methods are derived for the direct order reduction of PDE-models. This allows for an adaptive grid selection in the order reduction and thus increases the numerical efficiency of the corresponding approximation method. Furthermore, the degrees of freedom in the considered approximation techniques are determined such that system properties of interest are preserved.

Spillover prevention for early-lumping based compensator designs

A classical approach for the design of finite-dimensional compensators for infinite-dimensional systems is the early-lumping approach. Thereby, the compensator design is based on a finite-dimensional approximation of the plant. This can lead to the spillover problem, i. e. the resulting closed-loop system is unstable though the compensator stabilizes the corresponding approximation. In this research project new methods for the analysis of spillover are developed. Furthermore, easy to implement extensions are investigated for early-lumping-based compensators to prevent spillover.

Direct design of finite-dimensional compensators

Typically the design of compensators for distributed-parameter systems is based on the late-lumping or the early-lumping approach. Thereby, the resulting finite-dimensional compensator is obtained by using an approximation of an infinite-dimensional controller or of the infinite-dimensional plant. Consequently, the properties of the resulting closed-loop system have to be investigated after the design. In this research project finite-dimensional compensators are directly determined for infinite-dimensional systems. Since their design is not based on any approximation they directly achieve the desired specifications for the closed-loop system.

Feedforward control for the shallow water equations

In many practical applications the dynamics of a fluid can be modelled by the shallow water equations. In this research project new methods based on semi-discretizations and flatness-based techniques are developed for the feedforward control of these fluid models. The theoretical results are investigated by using a laboratory experiment that is shown below.

Laboratory experiment: round plexiglas cylinder with colored water. The simulation result for the water level is the yellow dashed line.
