A new technique for the digital control of continuous time systems is presented. This technique 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 a few thousand entries. The paper derives the control strategy and proposes a digital circuit to implement the controller. An example is presented in which the performance of a closed-loop digital controller is compared with that of an optimal regulator. The comparison shows that the performance of the new controller is very close to that of an equivalent optimal controller
