The paper characterizes the properties of discrete time minimax tracking control problem in the case of time varying references and disturbances. Hereunder, a multi step tracking control synthesis is suggested for linear time invariant (LTI) plants when the reference signal could be time dependent. Moreover, instead of directly rejecting the effect of the (time varying) disturbance signal, an intermediate...
The paper proposes a new, discrete time LQ optimal controller synthesis for output tracking over an infinite horizon. The resulted controller consists of a state feedback and a feedforward term. The solution requires a one step ahead prediction of the reference signal. For a smooth enough reference signal this can be replaced with extrapolation. Here, the properties for constant reference signals...
The paper suggests to apply a proper output weight to achieve guaranteed discrete algebraic Riccati equation (DARE) solvability of the LQ optimal control problem with output tracking. Usually a positive semi definite state weighting matrix (Q) is mentioned to be sufficient for solvable DARE. However, the literature also proposes more general rank conditions. The paper shows a sufficient condition...
In modern and innovative videoconference systems and human machine interfaces, localisation techniques play an important role for automatic camera and beamformer steering. Conventional acoustical and visual localisation techniques can be combined to form an audiovisual joint location estimate providing a more robust localisation of the active person. Tracking algorithms such as the well-known Kalman...
