Bifurcation control of nonlinear systems with time-periodic coefficients 具有时间周期系数非线性系统的分岔控制

In such systems, bifurcations occur when one of the Floquet multipliers becomes +1 , -1, or a pair of complex multipliers reaches magnitude 1. The stability of the bifurcated periodic or quasi-periodic orbit is guaranteed by employing a nonlinear state-feedback control. First the Lyapunov-Floquet transformation is applied such that the linear part of system equations becomes time-invariant. Then through an application of the time-periodic center manifold reduction and time-dependent normal form theory one can obtain a completely time-invariant form of the nonlinear equation for codimension one bifurcations. The time-invariant normal form is suitable for the application of control strategies developed for autonomous systems. Then by transforming the results back to the original variables, one obtains the gains for the time-varying controller. The control strategy is illustrated through an example of a parametrically excited simple pendulum undergoing a symmetry breaking bifurcation.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

The objective of the filter is to monitor certain faults called target faults and block other faults which are called nuisance faults. This filter is derived by keeping the ratio of the transmission from nuisance fault to the transmission from target fault small. It is shown that this filter approximates the properties of the classical fault detection filter such that in the limit where the ratio of the transmissions is zero, the optimal stochastic fault detection filter is equivalent to the unknown input observer if all invariant zero directions are included with the nuisance fault directions. Detection filter designs can be obtained for both linear time-invariant and time-varying systems.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

The feedback controller is updated at the same rate as the sampling rate of the output measurements. The feedforward controller processes the desired output signal for high accuracy tracking, and its output is updated at a rate N-times faster than the sampling rate of the output measurements. The discrete time model of the controlled plant may possess unstable zeros, and the zero phase error tracking controller is used as a feedforward controller. Inter-sample behavior of the plant is included in evaluating the tracking performance of the multi-rate system. Illustrative examples are given to show advantages of the proposed multi-rate feedback/feedforward control scheme.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

The result, when used within the standard IQC framework, is expected to be widely useful in nonlinear system analysis. For example, it enables \"discrimination\" between \"saturation-like\" and \"deadzone-like\" nonlinearities and can be used to prove stability of systems with saturation in cases when replacing the saturation block by another memoryless nonlinearity with equivalent slope restrictions makes the whole system unstable. In particular, it is shown that the L/sub 2/ gain of a unity feedback system with a rate limiter in the forward loop cannot exceed /spl radic/2.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

Recent work considered the use of a control horizon and polyhedral sets, and here we extend this approach to the more efficient formulation based on the autonomous system predictions.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.
