无源性和扇形边界
R2026b分析系统的无源性和任意锥扇形边界
在过程控制、远程操作、人机界面和系统网络等应用中，无源控制通常是安全需求的一部分。无源性是更一般的扇形边界概念的特例，其应用包括具有静态非线性的反馈系统的绝对稳定性。Control System Toolbox™ 包括分析无源性和任意扇形边界的动态系统的工具。

- 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.

- 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.
