Synthesis of Optimal Digital Controller for Continuous-Data Model-Following.
Abstract
The digitalization of flight control systems has been of increasing interest to the Air Force. One of the problems confronting the designer is the real-time implementation of advanced control algorithms within the computational capability of the on-board computer. In converting a continuous-data (analog) controller into a digital controller, ad hoc approaches such as bilinear transform and prewarped Tustin transform techniques have typically been used. These methods have the advantage of being straightforward and easy to use, and they are intuitively appealing. But the performance of a system digitalized by these approaches resembles the performance of the baseline (continuous) system only when the sampling frequency is relatively high, because the dynamics of the plant and the feedback structure of the system are not taken into consideration.
