Summary:This paper develops a new technique to the digital control of continuous systems. The new method is based on a table look up algorithm. To minimize the number of entries in the table a grid embedding process is proposed. Using this process, an accurate, fast, and low cost controller can be constructed using a table of only a few thousand entries. The paper derives the control strategy, proposes a digital circuit to implement the controller, and simulates the performance of the close loop system. The output of the close loop system is compared against that of an optimally regulater system. The comparison shows that the new controller performs very close to that of an equivalent optimal controller.
