Summary
This study introduces new methods for stabilizing asynchronous dual switching and semi-Markov jump systems. These techniques reduce conservatism and offer practical controller designs for complex real-world scenarios.
Area of Science:
- Control Theory

- System Stability
Background:
- Stochastic switching systems present unique challenges in stabilization due to asynchronous dynamics.
- Dual switching systems combine deterministic and stochastic dynamics, while semi-Markov jump systems involve time-dependent transitions.
Purpose of the Study:
- To develop novel stability criteria and controller design methods for asynchronous dual switching and semi-Markov jump systems.
- To address the challenges posed by inaccurate mode detection, time-varying delays, and uncertain transition probabilities.
Main Methods:
- Proposing new stability criteria that allow for controlled increases in Lyapunov functions during asynchronous intervals.
- Developing numerically testable asynchronous controller design methods for dual switching systems.
- Designing novel asynchronous controller methods for semi-Markov jump systems with bounded sojourn times.
Main Results:
- New stability criteria effectively handle asynchronous phenomena in both system types.
- The proposed controller design methods are practical for scenarios with mode mismatch and time delays.
- The methods for semi-Markov jump systems accommodate more realistic bounded sojourn times.
Conclusions:
- The developed techniques provide effective solutions for asynchronous stabilization problems in complex stochastic switching systems.

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

BIBO stability of continuous and discrete -time systems
497
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....
