Error Diagnosis in Dynamical Control Systems

    Project Details


    A control system generates control signals to a dynamical system, based on a number of measurements. The set of measurements are established by one or more sensors. The control signals change the behaviour of the dynamical system via a number of actuators. In several applications it is important to be able to determine whether the actuators and/or sensors fail. The present project studies analytical methods for determining whether the function of actuators and sensors are satisfactory, by investigating whether correlated values (in functional spaces) of control signal and measurements are consistent with the differential equations modelling the system. A number of results has been achieved, that reveals advantages and disadvantages in integrating the dimensioning process for control and diagnosis system. Moreover, explicit algorithms for the integrated design are given.
