We study the optimization of performance arbitrary periodically driven thermal machines. Within assumption fast modulation driving parameters, we derive optimal cycle that universally maximizes extracted power heat engines, cooling refrigerators, and in general any linear combination currents. denote this solution as ``generalized Otto cycle'' since it shares basic structure with standard cycle...
