When filters are stabilized or performance is sought to be improved, tuning of this matrix is the most common method. This tuning process cannot be done before the filter is implemented, as it is primarily made necessary by modelling errors. In this paper, two different methods for modelling the process noise are described and evaluated; a traditional one based on Gaussian noise models and a new one based on propagating modelling uncertainties. We discuss which method to use and how to tune the filter to achieve the lowest estimation error.","PeriodicalId":325193,"journal":{"name":"Proceedings of the 1999 IEEE International Conference on Control Applications (Cat.

First, a generalized approach to the standard RMM is proposed. Then, a new configuration for RMM that separates the robust compensator from the existing controller is proposed.

Gantry crane dynamics can often be effectively modeled as a single linear flexible mode. However, if the crane is equipped with a large-mass hook and the payload is sufficiently light, then the dynamics can become complicated by double-pendulum effects. This paper presents a method for determining the contribution of the second pendulum mode to the overall dynamic response. Furthermore, an input shaping scheme is developed to reduce residual oscillations. This control method utilizes the double-pendulum dynamics to determine the parameters of the input shaping algorithm.","PeriodicalId":325193,"journal":{"name":"Proceedings of the 1999 IEEE International Conference on Control Applications (Cat.

In particular, analysis and identification, as well as optimization and control of advanced aircraft are researched to attain the specified flying and handling qualities, guarantee survivability, damage adaptation and recovery, and improve mission effectiveness, etc. The paper reports a completely automated setup to perform real-time identification and control with failure accommodation. Innovative identification and design methods are applied. It is shown that the required aircraft performance through the specified operational envelope at various attitudes, including high-angle-of-attack regimes, can be achieved through real-time nonlinear analysis, identification, and control reconfiguration. An example is studied to demonstrate the practical use of the analytical and numerical results. In particular, the feasibility and viability of the identification and design methods developed, as well as the computational effectiveness and numerical stability of the algorithms, are illustrated. It is documented that the decision making process can be performed in real-time.","PeriodicalId":325193,"journal":{"name":"Proceedings of the 1999 IEEE International Conference on Control Applications (Cat.

In this approach, two matrices, S/sub FB/ and S/sub FF/, are calculated from the linear state space matrices and the optimal control gain. The S/sub FB/ and S/sub FF/ reveal the respective dominant feedback and ratio/feedforward paths of a system. Three screening and four performance heuristics have been developed to interpret these matrices to reveal the dominant control pathways of a system. Information gained from these matrices is used to formulate PI/FF control architecture(s). These architectures are tested on a fixed dynamic simulation to judge their performance. A continuous polymerization process was used as test case to evaluate the results of the optimal control based algorithm and to test the heuristics presented here. The algorithm identified weak manipulated variables and eliminated them from the list of degrees of freedom. It also identified viable potential control architectures that were tested with the fixed dynamic simulations. The algorithm provided information on each candidate architecture's simplicity and degree of decoupled, feedback-path dominance. These results, for each case, were confirmed through simulations.","PeriodicalId":325193,"journal":{"name":"Proceedings of the 1999 IEEE International Conference on Control Applications (Cat.
