Stable & Unstable Systems |Solved problems|
The document discusses stable and unstable systems in control systems. It defines a stable system as one where the system response remains bounded for a bounded input. An unstable system is defined as one where the output diverges to infinity or becomes unbounded for a bounded input. Control system theory focuses on estimating the stability of systems as stability determines a system's applicability.
On analyzing electrical systems
This document discusses various aspects of analyzing and troubleshooting electrical systems. It notes that to understand a system, one must learn both the big things like its function and power supply as well as the little things like wire routing and programming code. It also stresses the importance of understanding the system's environment and political context. The document provides tips for examining the internal components and wiring, as well as tracing individual circuits when drawings are unavailable. It notes that systems are increasingly controlled by programmable logic controllers (PLCs) which require understanding ladder logic programming in addition to the electrical components.
