Control Engineering

← Back to Domain-Specific Abstractions by Domain

8 domain-specific abstractions whose origin domain is Control Engineering.

• Bode plot — A paired logarithmic-frequency display of a linear system’s frequency-response magnitude and phase.
• Electro-pneumatic control — Couple electrical decision logic and sensing to pneumatic power through electrically actuated valves, so low-power signals sequence or regulate air-driven actuators.
• Fault detection and isolation — A control-engineering discipline that detects departures from expected system behavior and determines the likely fault type, location or component before recovery action.
• Fuzzy control system — A controller mapping imprecise linguistic input conditions to control actions through fuzzy sets, rules and defuzzification.
• Impulse vector — A phasor-like graphical representation of an input-shaper impulse's amplitude, phase and residual-vibration contribution, used to construct sequences whose vectors cancel.
• Iso-Damping — Shape a feedback loop so closed-loop damping and overshoot remain nearly invariant as loop gain moves the crossover frequency.
• PID controller — A feedback controller that combines proportional response to current error, integral response to accumulated error and derivative response to error trend.
• System identification — Construction of a mathematical dynamical-system model from measured input-output behavior and declared structural assumptions.
