Previously we (2000) have stated a characterization of the identifiability by considering this approach. The so-obtained identifiability necessary condition leads to the solution of partial differential equations. On the other hand, the identifiability sufficient condition may need an extra elimination. First, we elaborate the corresponding algorithm and in justifying it by some algebraic differential notions. Then its implementation is presented in a symbolic computation language.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.

The diagnosis system is based on the robust estimation of process outputs. A dynamic non-linear model of the process under investigation is obtained by a procedure exploiting Takagi-Sugeno (T-S) multiple-model fuzzy identification. The combined identification and residual generation schemes have robustness properties with respect to modelling uncertainty, disturbance and measurement noise, providing good sensitivity properties for fault detection and fault isolation. The identified system consists of a fuzzy combination of T-S models to detect changing plant operating conditions. Residual analysis and geometrical tests are then sufficient for fault detection and isolation, respectively. The procedure presented is applied to the problem of detecting and isolating faults in a benchmark simulation of a tank reactor chemical process.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.

The signal has an extremely slowly-decreasing frequency and is corrupted by white Gaussian noise, and also possibly by powerful tones. Four methods (the Hough transform, multiple frequency tracker, Page's test and EM algorithm) are explored. It is found that the Hough transform (HT) detector appears to be most suitable given constraints on computational load and detectability. It is compared with the GLRT, which is assumed to be as \"optimal\" as possible. Applying a suitable threshold for the HT can increase the speed dramatically while preserving the performance. We have found that for the HT detector both dithering (taking varied frequency shifts for FFTs) and increasing the FFT length can reduce the minimum detectable frequency slope with nearly no additional computation.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.

Our control strategy is based on sliding mode control. The design of a switching surface is based on Lyapunov techniques, and a variable structure control law is designed using the theory of sliding mode control. For the control we use a nonlinear mathematical model of a hydraulic system interacting with the environment. We try and consider most of the nonlinear and uncertain dynamics of this system in order to achieve robust performance over a range of operating conditions. The simulation results show that the proposed sliding mode controller is not sensitive to a large variation of parameters such as flow gain, supply pressure or environmental stiffness, and has an excellent tracking performance for various set point forces under uncertainties.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.
