Abstract
An automatic operation recovery system for automatically removing an operational failure caused in an apparatus whose complete operation is controlled by actuators operated in a predetermined sequence, thereby recovering the apparatus to its normal operating condition, comprises an actuator driver for controllably driving the actuators in a sequence suitable for a type of operational failure so as to remove the operational failure, a memory for accumulatively storing data of a type of operational failure and a sequence taken to remove the type of operational failure through the actuator driver and an automatic recovery controller for, when an operational failure is detected, assigning an order of priority to sequences available for removing the same type of operational failure accumulatively stored in the memory and automatically actuating the actuator driver to operate the actuators in a sequence assigned the first order of priority.
