Limit Cycle Bifurcation in Siso Control Systems with Saturation
نویسندگان
چکیده
The bifurcation of limit cycles in single-input single-output control systems with saturation is considered. Under some non-degeneracy conditions, a theorem characterizing such bifurcation is stated for the cases of dimension two and three. In terms of the deviation from the critical value of the bifurcation parameter, expressions in form of power series for the period, amplitude and the characteristic multipliers of the bifurcating limit cycle are obtained. These results are similar to the Hopf bifurcation theorem for differentiable systems, but they show some differences coming from the non-smooth character of the saturation characteristic.

متن کاملAnalysis and Control of Limit Cycle Bifurcations
The chapter addresses bifurcations of limit cycles for a general class of nonlinear control systems depending on parameters. A set of simple approximate analytical conditions characterizing all generic limit cycle bifurcations is determined via a first order harmonic balance analysis in a suitable frequency band. Moreover, due to the existing connection between limit cycle bifurcations and rout...

In this paper, an efficient method is presented to control the attitude of a satellite with ON-OFF actuator. The main objective of this novel method is to control the amplitude of the limit cycle which commonly appears in the steady state of such systems; and at the same time by consideration of real actuator constraints, reduce the fuel consumption of system. The Proposed method is a combinati...
متن کاملBifurcation of Limit Cycles from a Four-Dimensional Center in Control Systems
We study the bifurcation of limit cycles from the periodic orbits of a 4–dimensional center in a class of piecewise linear differential systems, which appears in a natural way in control theory. Our main result shows that three is an upper bound for the number of limit cycles, up to first order expansion of the displacement function with respect to the small parameter. Moreover, this upper boun...
متن کاملConstruction of generalized pendulum equations with prescribed maximum number of limit cycles of the second kind
Consider a class of planar autonomous differential systems with cylindric phase space which represent generalized pendulum equations. We describe a method to construct such systems with prescribed maximum number of limit cycles which are not contractible to a point (limit cycles of the second kind). The underlying idea consists in employing Dulac-Cherkas functions. We also show how this approac...
