Design of Control Systems
Controller Configurations
The car's cruise control system has essential controller configurations that ensure consistent speed while monitoring the surroundings and driver ...
PD Controller: Design
In car suspension systems, Proportional Derivative controllers are utilized to adjust the damping force in response to road conditions.
A controller, ...
Time-Domain Interpretation of PD Control
Consider a motor system with only proportional control that exhibits high maximum overshoot and oscillation, reflected in the error signal and its rate of ...
Frequency-Domain Interpretation of PD Control
Considering a fan as the control system, a Bode plot can visually represent the PD controller through a transfer function.
The frequency domain ...
PI Controller: Design
In applications like automatic brightness adjustment on smartphones, Proportional Integral controllers effectively mitigate steady-state errors for ...
Time and frequency -Domain Interpretation of PI Control
Everyday devices like thermostats utilize PI controllers. These can enhance system damping and reduce steady-state error when the controller transfer ...
PID Controller
A PID controller thermostat adjusts heating or cooling based on the temperature gap between actual and desired levels.
A PD controller, found in car speed ...
Phase-lead and Phase-lag Controllers
Imagine adjusting the volume equalizer on a stereo. When the bass is cranked up, a phase-lead controller is at work. When the treble is increased, a ...
Time and frequency -Domain Interpretation of Phase-lead Control
Consider adjusting the brightness on a television screen. When the contrast is enhanced, a phase-lead controller is at work.
Mathematically, if the first ...
Time and frequency -Domain Interpretation of Phase-lag Control
Consider a dimmer switch controlling the brightness of a light bulb. This exemplifies phase-lag control, where the brightness of the bulb is gradually ...
