This paper treats the problem of an adaptive fuzzy control of continuous nonlinear systems which contain unknown constant parameters in their state space. These systems are represented by Takagi-Sugeno fuzzy model. The quadratic Lyapunov function is used in the stability analysis and the design of fuzzy controllers. A common symmetric positive definite Lyapunov matrix allows us to determine an update...
In this paper, a robust Hinfin controller is designed and applied to a DC motor in speed control framework. The performance and robustness aspects of controlled system related to modelling uncertainties and external disturbances are the particular attention. In a frequency formalism, the recourse to the sensitivity functions, as tool of study, leads to develop frequency templates translating the performance...
Proportional-integral-derivative (PID) controllers are widely used in automation systems. They are usually implemented either in hardware using analog components or in software using computer-based systems. They may also be implemented using Application Specific Integrated Circuits (ASICs). This paper outlines a methodology for building PID controllers on field programmable gate arrays (FPGAs) which...
