Projection-based integrators for improved motion control: Formalization, well-posedness and stability of hybrid integrator-gain systems

چکیده
In this paper we formally describe the hybrid integrator-gain system (HIGS), which is a nonlinear integrator designed to avoid limitations typically associated with linear integrators. The HIGS keeps sign of its input and output equal, thereby inducing less phase lag than integrator, much like famous Clegg integrator. achieves reduced by projection controller dynamics instead using resets state, forms potential benefit control element. To analyze HIGS-controlled systems, present an appropriate mathematical framework for describing these novel systems. Based on framework, systems are proven be well-posed in sense existence forward completeness solutions. Moreover, propose two approaches analyzing (input-to-state) stability resulting closed-loop systems: (i) circle-criterion-like conditions based (measured) frequency response data, (ii) LMI-based exploiting new construction piecewise quadratic Lyapunov functions. A motion example used illustrate results.

Control Design for Integrator Hybrid Systems
We define controllability for hybrid systems as the existence of correct control-laws that transfer the hybrid plant between pre-defined subsets of the hybrid state-space. A methodology for analyzing controllability and synthesizing control-laws for a class of hybrid systems, applicable expecially in batch control, is proposed. We use a framework consisting of a hybrid plant and a hybrid contro...
متن کاملWell-posedness and Stability Analysis of Hybrid Feedback Systems Using Shkalikov’s Theory
The modern method of analysis of the distributed parameter systems relies on the transformation of the dynamical model to an abstract differential equation on an appropriately chosen Banach or, if possible, Hilbert space. A linear dynamical model in the form of a first order abstract differential equation is considered to be well-posed if its right-hand side generates a strongly continuous semi...

متن کاملWell-posedness of the Complementarity Class of Hybrid Systems
One of the most fundamental properties of any class of dynamical systems is the study of well-posedness, i.e. the existence and uniqueness of a particular type of solution trajectories given an initial state. In case of interaction between continuous dynamics and discrete transitions this issue becomes highly non-trivial. In this survey an overview is given of the well-posedness results for com...
