In this paper, the design of an on-chip Fault Detection and Diagnosis System for Condition Based Maintenance of electromechanical actuators is presented. The proposed system is based on signal processing algorithms integrated in a customized Application Specific Integrated Circuit (ASIC). The design was synthesized using a 90nm CMOS standard cell library. As a case study, post-synthesis simulations were performed using signals acquired from a real electromechanical valve, using torque and vibration sensors considering both fault-free and defective situations for the actuator. Results show the effectiveness of the system in performing real-time fault detection and identification, with low power consumption and low silicon area utilization.
