![]() ![]() In order to implement our temperature control system, we technically don't need a model of our plant (the lightbulb). To Proportional (P) control, Proportional-Integral (PI) control, and first-order systems. The chatter, through the use of deadbands, low-pass filters, and Pulse-Width Modulation. In this experiment, we observe the resulting "chattering"īehavior of the lightbulb and investigate alternative methodologies for reducing the frequency of this chatter, or smoothing To the AC source or it is not its intensity cannot be modulated. The lightbulb is a binary system with only two states, on or off. Is increased by turning the lightbulb on and the lightbulb's temperature is decreased by turning the lightbulb off (up toĮnvironmental limits). The purpose of this activity with the lightbulb is to demonstrate how to control switched systems. The lightbulb's temperature and the control signal. The control logicĮmployed for determining when to switch the relay on and off is implemented within Simulink, which is also employed for visualizing That is, the digital output alternately connects and disconnects the lightīulb from the AC power source (from the wall) via the relay in order to turn the light bulb on and off. The Arduino board is also used for generating the Digital Output that switches the solid-state relay on and off. The Arduino board provides power to the sensor and reads the sensor output via an Analog Input. The temperature of the lightbulb is measured in this example with a TMP36 sensor (cheap, relatively accurate, sufficient range). AC solid-state relay (hockey-puck type, etc.).lightbulb (incandescent, LED, CFL, etc.).
