Preventive Controller Switchover

A preventive switchover from a primary controller to a secondary controller even before the primary controller fails system and method includes a server that collects log files comprising operational parameters of the primary controller from the primary controller in real-time. The server determines abnormal patterns or signatures in the operational parameters of the primary controller by comparing the operational parameters with reference patterns or signatures. The reference patterns or signatures are generated by training one or more Artificial Intelligence (AI) based models. After determining the abnormal patterns or signatures, the server predicts events that will lead to switchover from the primary controller to the secondary controller. Thereafter, the server provides a signal to the primary controller to perform preventive switchover to the secondary controller before the primary controller fails.
