This paper presents the method of discrete-time sliding mode control (DT-SMC) for a class of nonlinear time-delay systems via Takagi-Sugeno (T-S) fuzzy model. First, the discrete-time linear model with uncertainties and tine-varying delay is derived by employing T-S model to represent original system. Then the control problem becomes the robust stabilization controller design for linear uncertain...
In charge-pump phase-locked loops (CP-PLLs), the reference signal samples the phase delay between reference and feedback signals. When a frequency divider is present in the loop, the spectrum folding of the voltage-controlled oscillator phase noise caused by the inherent subsampling operation adds a relevant contribution to the in-band output noise. This brief elaborates the discrete-time linear model...
The design of a indirect self-tuning power system nodal voltage regulator is presented. A recursive least-squares (RLS) algorithm with variable forgetting factor estimates at each sampling period the parameters of a suitable discrete-time linear model that describes in an approximated way the system dynamics from the regulation node. The proposed model comprises both an unknown bias representing the...
