Abstract
A triple modular redundant control system which uses four controllers coupled in sets of two parallel controllers on relatively positive and relatively negative sides of a load. One of the controllers on one side of the load is energized only when both of the controllers on another side of the load are energized. The system implements a 2-out-of-3 logic function using only four controllers. The system includes a self-testing feature which allows the controllers to be tested even while a load is being operated without creating undue perturbations in load operation.
