By taking the faster sampling of the plant output than the control input, we can give a SIMO model representation. It is clarified that the SIMO structure can provide a new identification scheme to identify an unstable plant in closed-loop. One of the advantages is that the proposed identification method can remove the ordinary restrictive identifiability condition, and does not require that the reference input hold the persistently exciting (PE) property. Thus only one inter-sampling of the plant output can assure the identifiability of the plant parameters.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

Such an interpretation is particularly attractive in the context of physical control problems with a naturally occurring process which is well modelled in the stochastic sense. The extremely important case of civil structures assailed by earthquakes, wind, and seas is precisely such a problem. This paper considers a state-feedback solution to the LQG version of this problem class. The formulation is parametrized by the number k of cumulants chosen for design. A general solution of this k-cumulant problem, together with studies of its application to the SDOF system described by Chung et al. (1988), is the subject of this work.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

Lagrange stability) properties of the switched system are preserved in the presence of certain kinds of vanishing perturbations (resp., nonvanishing perturbations). The analysis is possible since the conic switching laws always possess certain kinds of \"quasiperiodic switching operations\". We also propose for a class of nonlinear second-order switched systems with time-invariant subsystems a switching control law which locally exponentially stabilizes the entire nonlinear switched system, provided that the conic switching law exponentially stabilizes the linearized switched systems (consisting of the linearization of each nonlinear subsystem). This switched control law is robust in the sense mentioned above.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

Of many possible benefits from the three civilian signals, this paper focuses on how to achieve high integrity and continuity in local area differential navigation by using multiple combinations of the carrier wave frequencies of the signals. The carrier frequencies of the three civil signals can be used to form measurements with different wavelengths, both longer and shorter than their own, depending on the specific combination used. By using these combinations in cascade manner, first finding the integer of the signal with the longest wavelength then moving on to a shorter one, the L1 integer can be resolved without using redundant measurements. Since integrity and continuity of differential carrier phase navigation depends on the validity of the integer solution, an integer rounding criterion based on wavelength and measurement noise is developed to verify the solution. Analysis of the integer rounding criterion shows that multiple levels of integrity and continuity for differential carrier phase navigation are possible, depending on the measurement noise level. Sensitivity analysis is carried out to study the effect of receiver noise, multipath delay, ionosphere delay and change in distance between an user and a reference receiver.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

The relative gain array is used to assess coupling and the functional controllability analysis uses the methodology of Skogestad and Postlethwaite (1996). This determines if adequate levels of disturbance rejection can be achieved with allowable levels of manipulation. The aim is to understand the fundamental properties of the process which limit the ability of the control system to reject disturbances. A first principles model of appropriate complexity which captures the essential mechanism is developed and used.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.
