writeSpeed

Write speed of PID motor

Since R2020a

Add-On Required: This feature requires the MATLAB Support Package for Arduino Hardware add-on.

Syntax

writeSpeed(pidObj,speed)

Description

writeSpeed(pidObj,speed) drives the DC motor connected to the motor number corresponding to PID number of PID motor object in closed-loop control while receiving feedback from encoder channel corresponding to PID number at the specified speed.

Set Speed of DC Motor in Closed-Loop Control

This example uses:

MATLAB Support Package for Arduino Hardware MATLAB Support Package for Arduino Hardware

Open Live Script

Create a connection to the Nano Motor Carrier.

arduinoObj = arduino('/dev/ttyACM0','Nano33IoT','Libraries','MotorCarrier');
mcObj = motorCarrier(arduinoObj);

Create a connection to the PID Motor in speed control mode.

pidObj = pidMotor(mcObj,1);

Set the speed of the DC Motor M1 in closed-loop control with feedback from encoder channel 1 to 100 RPM

writeSpeed(pidObj,100);

Input Arguments

`pidObj` — PID motor object
object

Connection to the PID motor on MKR Motor Carrier or Nano Motor Carrier in the speed control mode, specified as an object.

`speed` — Speed of PID motor
numeric

Speed of the motor, specified in revolutions per minute (RPM).
