Since it is important to reduce the cost of the active noise control systems for practical use, the sampled-data H/sub /spl infin// control synthesis is applied to design a digital controller with long sampling period. As a conventional synthesis method, continuous-time H/sub /spl infin// control based synthesis is also applied, where the Tustin transformation is used to discretize continuous-time H/sub /spl infin// controllers. The experimental results show that the conventional method work well for short sampling period, however, when the sampling period is not short enough, the system loose stability. In contrast, the sampled-data H/sub /spl infin// control synthesis does not cause such problems, and longer sampling period is achieved without performance degradation compared to the conventional method.","PeriodicalId":371853,"journal":{"name":"42nd IEEE International Conference on Decision and Control (IEEE Cat.

The uncertainty models presented in this paper use the knowledge of a stabilizing feedback controller to structure and formulate the uncertainty on a model. Subsequently, the controller dependent coprime factor uncertainty model can be used to formulate model (in)validation tests on the basis of closed-loop data. The model (in)validation is performed on sample data from a flexible structure to illustrate the presented model validation results. An open-loop based uncertainty model is also used to demonstrate the benefits of closed-loop uncertainty modeling over open-loop uncertainty modeling.","PeriodicalId":371853,"journal":{"name":"42nd IEEE International Conference on Decision and Control (IEEE Cat.

Robust quantization for digital finite communication bandwidth (DFCB) control 数字有限通信带宽控制的鲁棒量化

Because of the possibly unpredictable fluctuation of the data rate, we are interested in feedback control designs that tolerate significantly constrained data-rates on feedback loops, while providing acceptable performance when such data rate constraints are not in force. In light of a very basic notion of acceptable performance, we show that control designs with different number of quantization levels tolerate constrained data rates differently. This leads to the conclusion that binary control represents the most robust control quantization under data rate constraints imposed by time-varying congestion on the feedback communication channel. The advantage margin of binary control is further investigated numerically with and without the sampling-control asynchronism being considered. We show that the advantage margin is more substantial when the sampling-control asynchronism is significant.","PeriodicalId":371853,"journal":{"name":"42nd IEEE International Conference on Decision and Control (IEEE Cat.

The considered interconnection structure can represent Hammerstein, Wiener or Lur'e models, as well as more complex structures. A key feature of the proposed method is that the nonlinear subsystem may be dynamic and is not supposed to have a given parametric form. In this way the complexity/accuracy problems posed by the proper choice of the suitable parameterization of the nonlinear subsystem are circumvented. Moreover, the cost function used to evaluate identification errors is guaranteed to decrease for increasing number of iterations. The effectiveness of the algorithm is tested on the problem of identifying a simulated half-car model for vertical dynamics of vehicles with controlled suspensions. Assuming an experimental setup easily realizable in actual experiment on real cars, the half-car model is decomposed as a generalized Lur'e system, consisting of a linear MIMO system, connected in a feedback form with a MIMO nonlinear dynamic system through not measured signals.","PeriodicalId":371853,"journal":{"name":"42nd IEEE International Conference on Decision and Control (IEEE Cat.

The objective is to find the combination of escape maneuvers between two aircraft that attains the largest minimum separation distance among all the possible choices of escape maneuvers. To achieve this objective, a terminal optimal control problem with a quadratic performance criteria is formulated where the terminal time is set to be the time at the minimum separation. The commands for an escape maneuver consist of a normal acceleration command and a roll rate command. To simplify the problem, the maximum allowable normal acceleration is commanded in the pitch axis, hence the command inputs appeared in the cost functional is formulated only with the roll rate commands. The optimal roll rate commands are determined by solving the Euler-Lagrange equations.","PeriodicalId":371853,"journal":{"name":"42nd IEEE International Conference on Decision and Control (IEEE Cat.

The focus here is on continuous evasion where the agent does not have the benefit of a target zone (e.g., a shelter) which up on reaching it can discontinue engaging the pursuers.
