Systems Examples of essentially nonlinear phenomena • Finite escape time, i.e, the state can go to infinity in finite time (while this is impossible to happen for linear systems) • Multiple isolated equilibria, while linear systems can only have one isolated equilibrium point, that is...
This established and authoritative text focuses on the design and analysis of nonlinear control systems. The author considers the latest research results and techniques in this updated and extended edition. Examples are given from mechanical, electrical and aerospace engineering. The approach consists of...
Feedback controlInvarianceNonlinear systemsPerturbationRotating bodiesParticlesPotential fieldsRigid structuresVectors (Mathematics)Two examples of disturbance decoupling for nonlinear systems are analyzed using the concept of controlled invariance. In the first example a feedback is explicitly constructed which ...
This book explains in detail the concepts, theorems and algorithms in nonlinear control theory, illustrated by step-by-step examples. In addition, all the mathematical formulation involved in deriving the nonlinear control laws of power systems are sufficiently presented. Considerations and cautions ...
To relax the feasibility conditions, asymmetric error bounds are considered and asymmetric barrier functions are used for control design. The performance of the BLF-based control is illustrated with two simulated examples. 展开 关键词: constrained systems adaptive control backstepping barrier functions ...
Simple examples illustrate some properties of the controller. Furthermore, the control strategy is applied to the stabilization of a gas-lifted oil well, and simulations on a rigorous multi-phase dynamic simulator of such a well demonstrate the controller performance. 展开 关键词: Reglerteknik ...
The three non-flat examples, the simple, double and variable length pendulums, are borrowed from non-linear physics. A high frequency control strategy is proposed such that the averaged systems become flat. 展开 关键词: Nonlinear control systems System theory Feedback Linearization Controllability ...
Clearly, the frequency-response concept of linear systems must be modified for nonlinear applications. Hysteresis Multivalued functions exist when two or more function values correspond to the value of the variable. Multivalued functions are intrinsically nonlinear. Examples of this are the hysteresis ...
