Feedback control indirect response models
Journal of Pharmacokinetics and Pharmacodynamics, 2016A general framework is introduced for modeling pharmacodynamic processes that are subject to autoregulation, which combines the indirect response (IDR) model approach with methods from classical feedback control of engineered systems. The canonical IDR models are modified to incorporate linear combinations of feedback control terms related to the time ...

Feasibility Conditions for Indirect Feedback Passivation
International Journal of Robust and Nonlinear Control, 2023ABSTRACTThis paper studies feasibility conditions for making a single‐input‐single‐output system non‐strictly indirectly passive (positive real) with respect to an external input by state feedback, which is an extension from the strictly positive real feasibility conditions but is more challenging.

Indirect negative feedback bipolar LNA
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003In this paper, an indirect negative feedback (INF) technique is adopted in the design of a low-noise amplifier (LNA) suitable for low-voltage wireless communication applications. It is shown in this paper that INF is suitable to achieve an acceptable performance of LNA's in low-voltage operation.

A Broadband Indirect-Feedback Power-to-Current LNA
2006 IEEE International Symposium on Circuits and Systems, 2006A dual-loop resistive-feedback power-to-current amplifier circuit to be implemented in SiGe or GaAs IC technology is presented. Simulation results indicate that any technology process with NFmin 20 GHz is able to achieve an overall noise figure less than 0.5 dB, an input return loss less than -15 dB and flat gain over a frequency range from 0.6 GHz ...

Direct and indirect output feedback design for TORA system
2014 American Control Conference, 2014This paper addresses the problem of stabilizing a TORA system without velocity measurement. For this purpose, two classes of output feedback designs, direct and indirect, are employed to design a nonlinear observer for estimating an unavailable variable (velocity variable).

An Efficient Indirect Identification Method for Feedback Control System
2008 IEEE International Conference on Networking, Sensing and Control, 2008In many cases it is not possible to remove the feedback during an identification experiment because this may lead to instability. The feedback may also be inherent in many dynamic systems (e.g., economical, biological). In this paper we shall consider the problem of identification of dynamic systems operating under feedback control and propose an ...
