A simple algorithm for establishing the presence of points common to some singularity (hyper)surfaces associated to covariance matrices is developed. It allows, on the basis of the new algebraic and geometric properties recently given by Guidorzi (1994), the computation of the maximal number of linear relations that can be associated to a given set of data.

In this paper, a combined method of change detection and failure decision is proposed for the system under the adaptive control based on the self-tuning regulator. The controlled system is assumed encounter unexpected parameter changes, which may be caused by a failure or a normal operation. Such a system change can effectively be detected by using Fullback Discrimination Information (KDI) as an index for model discrimination. In order to decide whether the detected system change is caused by a failure or not, a neural network approach to failure decision is introduced. Based on the knowledge about failure modes and system operations, the regulator parameter variations after the change detection are used as training data for the network learning. In this way an on-line monitoring scheme of adaptively controlled systems can be established. Simulation studies of a second-order damped oscillator have been earned out to demonstrate the effectiveness of the method.
In this paper, we describe the fault tolerant schemes for the multistage interconnection network (MIN) and its fault diagnosis. Firstly, we present a fault tolerant MIN and a adaptive self-routing scheme for the netwo...

In this paper, a quick identification method based on the short time record of input-output data is introduced for joint state and parameter estimation of nonlinear continuous-time systems. The method can then be used for on-line monitoring the system with unknown parameters. An application way of the method to main-steam temperature control of a thermal power plant are developed in the framework of model reference adaptive control system (MRACS). Simulation studies on a super-heater model have been carried out to demonstrate the effectiveness of the proposed method.

The paper presents an experimental identification of the parameters of a load of a manipulator gripper: mass; static moment coordinates; and six inertial parameters. The experiments have been carried out for an ASEA IRp-6 robot equipped with a German DLR and American JR3 force/torque sensors. An external measurement system for monitoring each motor's position, velocity and current has also been employed. Two identification models, differential and integral, have been depicted. The results of both static (i.e. when the manipulator is at rest) and dynamic (i.e. when the manipulator moves along a predefined trajectory) are presented.< >
