All approaches to optimal experiment design for control have so far focused on deriving an input signal (or input signal spectrum) that minimizes some control-oriented measure of plant/model mismatch between the nominal closed loop system and the actual closed loop system, typically under a constraint on the total input power. In practical terms, this(More)
This paper addresses robust deconvolution filtering when the system and noise dynamics are obtained by parametric system identification. Consistent with standard identificationmethods, the uncertainty in the estimated parameters is represented by an ellipsoidal uncertainty region. Three problems are considered: (1) computation of the worst case H2(More)
The goal of this paper is on the one hand to give a tutorial on the main ideas of a recently introduced paradigm for optimal experiment design whose objective is to design the least costly identification experiment while guaranteeing a sufficiently accurate model for e.g. control. On the other hand, the second goal is to illustrate with well chosen examples(More)
The printing quality delivered by a Drop-onDemand (DoD) inkjet printhead is mainly limited due to the residual oscillations in the ink channel. The maximal jetting frequency of a DoD inkjet printhead can be increased by quickly damping the residual oscillations and by bringing in this way the ink-channel to rest after jetting the ink drop. The inkjet(More)
This brief addresses the problem of clock generation and distribution in globally synchronous locally synchronous chips. A novel architecture of clock generation based on network of coupled all-digital PLLs is proposed. Solutions are proposed to overcome the issues of stability and undesirable synchronized modes (modelocks) of high-order bidirectional PLL(More)
