The main objective of this book was to introduce a new approach to the design of stable digital control systems which is achieved by using a global digital re-design method for converting an analog control system into a digital one is called plant input mapping (PIM).The main advantages of the new approach are the guaranteed closed-loop stability for almost all sampling periods, and the recovery of the continuous-time performance when the sampling period approaches zero. The result guarantees closed loop stability for all non-pathological sampling periods. On the other hand the major...
