Early-lumping based controller synthesis for linear infinite-dimensional systems

Meer over het boek

Controllers for systems with spatially distributed parameters are often designed on the basis of an approximation model. Doing so, the neglected system dynamics might have a negative impact on the closed-loop behavior. This dissertation presents several approaches to deal with this undesired effect in a systematic way. These address continuous-time as well as discrete-time compensators with particular low order. The considered system class covers a variety of linear parabolic, hyperbolic, and biharmonic systems with spatially distributed inputs and outputs, as well as a class of time-delay systems. The dynamics of these systems and the closed-loop behavior are represented on the basis of state space models. The applied functional analytic tools are explained in detail.
