Comments on "State-Feedback Control of Fuzzy Discrete-Event Systems
Abstract:
The above paper considers the state-feedback control problem of fuzzy discrete-event systems (DESs) (FDESs) and gives a necessary and sufficient condition for the existence of a state-feedback controller. In this correspondence paper, after indicating that the problem under consideration is applicable for general DESs, not limited to FDESs, we show that the condition given in the above paper is not necessary by a counterexample and then provide a necessary and sufficient condition for the existence of a state-feedback controller.

Feedback control systems
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...
Effects of feedback
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Open and closed-loop control systems
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...
