Sensor and actuator self-validation is a critical step in system control and fault diagnostics. If sensors do not work properly, one cannot rely on their outputs to further deduce system status. Similarly, faulty actuators will not satisfy system performance objectives and may cause disasters in feedback control systems. In this paper, a novel method to generate structured residuals for isolating sensor and actuator failures with the least sensitivity to model-plant-mismatch (MPM) and… CONTINUE READING
