Pasividad y límites de sectores

Analice la pasividad y los límites de sectores cónicos arbitrarios de los sistemas

El control pasivo a menudo forma parte de los requisitos de seguridad en aplicaciones como el control de procesos, la teleoperación, las interfaces persona-máquina y las redes de sistemas. La pasividad es un caso concreto de la noción más general de los límites de sectores, cuyas aplicaciones incluyen estabilidad absoluta de los sistemas de feedback con no linealidades estáticas. Control System Toolbox™ incluye herramientas para analizar la pasividad y los límites de sectores arbitrarios de los sistemas dinámicos.

Pasividad

About Passivity and Passivity Indices

A system is passive if it cannot produce energy on its own, and can only dissipate the energy that is stored in it initially. Passive control has applications such as process control, tele-operation, and human-machine interfaces.

Passivity Indices

Compute various measures of passivity for linear time-invariant systems.

Parallel Interconnection of Passive Systems

The parallel interconnection of passive systems is also passive.

Series Interconnection of Passive Systems

The series interconnection of passive systems is not necessarily passive.

Feedback Interconnection of Passive Systems

The feedback interconnection of passive systems is also passive.

Límites de sectores

About Sector Bounds and Sector Indices

Sector bounds are constraints on the I/O trajectories of a system. Sector indices provide measures of how well a system’s trajectories fit into a particular sector.

Absolute Stability for Quantized System

This example shows how to enforce absolute stability when a linear time-invariant system is in feedback interconnection with a static nonlinearity that belongs to a conic sector.
