To provide reliability in the event of failures, modern aircraft control schemes are redundant, with two or three control laws for each application. This chapter addresses the design of digital, or discrete‐time, controllers. First, it discusses the simulation of digital controllers on a digital computer. In the first approach to digital control design, the chapter shows how to convert a continuous‐time controller to a digital controller using the bilinear transform (BLT) and matched pole‐zero (MPZ) technique. As a second approach, it shows how the design of the continuous‐time controller may be modified to take into account some properties of the sampling process as well as computation delays. Discretization of such a modified continuous controller yields a digital control system with improved performance. Finally, the chapter discusses some implementation considerations, such as actuator saturation and controller structure.
