Abstract :
Investigates the concept of discrete-time models of continuous-time systems. The framework proposed applies to linear, time-invariant systems as well as to triangular nonlinear systems. Numerical examples of nonlinear triangular systems illustrate the concepts involved. Discretization of the average model of a PWM-regulated rectifier is considered. Furthermore, the impact of the combinations of different hold functions with respect to accuracy and complexity is analyzed for the simulations of a nonlinear RLC circuit
