Abstract :
The predictive first order hold circuit is introduced and analyzed. The main advantage of this hold circuit is that it gives a continuous control signal. Conditions for causality and a pole placement procedure are presented. Formulas for sampling a linear quadratic Gaussian (LQG) problem are given and are used to analyze an example where the predictive first order hold gives better performance than the best zero order hold control law
