Feedback control systems

Feedback control systems

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Open and closed-loop control systems

Open and closed-loop control systems

Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal and...

Control Systems

Control Systems

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.
At the heart...

BIBO stability of continuous and discrete -time systems

BIBO stability of continuous and discrete -time systems

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.

Linear time-invariant Systems

Linear time-invariant Systems

A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be calculated...

Multi-input and Multi-variable systems

Multi-input and Multi-variable systems

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence of...

Background:

Boolean Control Networks (BCNs) are crucial for modeling genetic regulatory networks.
Implementing BCNs faces challenges due to stochasticity and measurement noise, complicating output tracking.
Deterministic state estimation is insufficient for these complex systems.

Purpose of the Study:

To develop a unified probabilistic control framework for robust output tracking in BCNs.
To address dual uncertainties from asynchronous updates and output measurement noise.
To shift from deterministic state estimation to a belief state representation.

Main Methods:

A belief-state observer was developed using the semi-tensor product and recursive Bayesian inference.
The observer reconstructs the full posterior probability distribution over network states.
A belief-based Model Predictive Control strategy was introduced for optimal control sequence generation.

Main Results:

The proposed observer effectively discards output measurement noise and resolves hidden-state ambiguities.
The belief-based Model Predictive Control strategy achieves robust output tracking.
Theoretical analysis guarantees the mean-square boundedness and stability of the closed-loop system.

Conclusions:

The unified probabilistic framework provides a robust solution for output tracking in BCNs.
The method is validated on biological regulatory networks, demonstrating its efficacy and robustness.
This approach advances the control of complex genetic networks.
