Limit Cycle Walking

This chapter introduces the paradigm `Limit Cycle Walking'. This paradigm for the design and control of two-legged walking robots can lead to unprecedented performance in terms of speed, efficiency, disturbance rejection and versatility. This is possible because this paradigm imposes fewer artificial constraints to the robot's walking motion compared to other existing paradigms. The application...

Energy Conservative Limit Cycle Oscillations

This paper shows how globally attractive limit cycle oscillations can be induced in a system with a nonlinear feedback element. Based on the same principle as the Van der Pol oscillator, the feedback behaves as a negative damping for low velocities but as an ordinary damper for high velocities. This nonlinear damper can be physically implemented with a continuous variable transmission and a spr...

Analysis 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...

Modeling and Detection of Limit-Cycle Oscillations Using Adaptable Linear Models

A method for modeling the flutter response of a thin winged aircraft is presented. A hybrid physical-adaptive modeling framework is proposed to separate the autoregressive and moving average flutter components. Adaptive oscillators set at the structural free-vibration modal frequencies of the wing represent the structure (the autoregressive component). The moving average filters represent signa...

Test Models for Statistical Inference: Two-Dimensional Reaction Systems Displaying Limit Cycle Bifurcations and Bistability

Theoretical results regarding two-dimensional ordinary-differential equations (ODEs) with second-degree polynomial right-hand sides are summarized, with a focus on multistability, limit cycles and limit cycle bifurcations. The results are then used for construction of two reaction systems, which are at the deterministic level described by twodimensional third-degree kinetic ODEs. The first syst...
