This article represents sonological research activities from the inception and development of an electroacoustic feedback system instrument to the migration and integration of real-time computational feedback system methods and techniques for the production of complex sounds. It provides sound samples, spectrographic analysis, methods, materials and results, and discusses unique sound phenomenon generated by an indeterminate (chaotic) feedback system and electroacoustic computer feedback system instrument. The study seeks to convey new methods and techniques for the synthesis of sound and provide methods of interacting with a chaotic feedback synthesis system for optimal iterative phenomenon generation and observation.
This paper provides a new μ analysis and synthesis method of state feedback systems. First, we derive a necessary and sufficient condition for the system to have μ less than a specified valu γ by using parameter-dependent multipliers and the positive real lemma. Furthermore we give a computable sufficient condition which requires no more computation burden while being less conservative than former methods. Second, based on these results, we give an LMI condition for the existence of a state feedback gain which achieves that μ of the closed loop system is less than given γ. Finally, an illustrative numerical example is given.
Feedback Control System Analysis and Synthesis: ..
In the generative state of a feedback system, loop gain is increased and seeded with sound, coaxing the system into oscillation, but not to the extent that it causes catastrophic oscillation of the system, where system failure or damage would result.
Feedback control system analysis and synthesis
To fully isolate and create the self-generating sound signatures, a non-interferential approach is used, avoiding quantum observational effects (that the observation of one aspect of a particle introduces uncertainty in other simultaneous measurements) or unintended consequences (outcomes that are not intended by a purposeful action) in interacting with the chaotic feedback system. This approach will improve the production of fractal sound forms in an open or tuned, positive or negative feedback, closed loop electroacoustic-computational feedback synthesis system and loop.

An electroacoustic feedback synthesis system instrument is shown in Figure 3, in the normalized form. The forward path of the feedback system begins after the summing point, where the line level feedback path output is routed to a power amplifier, then to the nozzle transducer using a run of speaker cable and spade connectors (bottom of plate). The amplifier to the nozzle transducer is matched in power and impedance (8 ohm, 25 watts) for maximum power transfer. This completes the basic chaotic instrument feedback system loop.

This book provides a wide variety of state-space--based numerical algorithms for the synthesis of feedback algorithms for linear systems with input saturation. Specifically, it addresses and solves the anti-windup problem, presenting the objectives and terminology of the problem, the mathematical tools behind anti-windup algorithms, and more than twenty algorithms for anti-windup synthesis, illustrated with examples. Luca Zaccarian and Andrew Teel's modern method--combining a state-space approach with algorithms generated by solving linear matrix inequalities--treats MIMO and SISO systems with equal ease. The book, aimed at control engineers as well as graduate students, ranges from very simple anti-windup construction to sophisticated anti-windup algorithms for nonlinear systems.
