Original Kurzfassung:
This contribution is concerned with the observability and accessibility analysis of implicit discrete-time dynamic systems. The presented approach is motivated by a geometric representation of discrete-time systems and the crucial observation that the Lie group investigations known for implicit continuous-time dynamic systems is also appropriate in the discrete-time scenario. The obtained formal method to state conditions for local observability and accessibility allows can be done by computer algebra. Furthermore, a nonlinear discrete-time controller design is discussed by considering the class of input-to-state linearizable continuous-time control systems. This approach is based on the calculation of a control sequence such that the system trajectories considered at equidistant time steps coincide with those of linear discrete-time one.
