Electronic Circuits IX: Feedback Control and Stability Margins Step by Step
A lightweight execution-visualization book.
The Feedback Ledger
Feedback Subtracts a Measurement
Controller Gain Drives the Error
Closed Loop Output Solves the Ledger
Loop Gain, Sensors, and Limits
More Forward Gain Reduces Error
Sensor Scale Changes the Loop Equation
Actuator Limits Break the Ideal Loop
