robotino_motor_dialog

 

Parameter

Description

Acceleration

Acceleration/Deceleration factor. With the maximum value 100 speed set-points are given directly to the motor's controller. With smaller values differences between speed set-points are flattened over time. This can be used to generate smooth motions of Robotino.

kp

Proportional term of the motor's PID controller

ki

Integral term of the motor's PID controller

kd

Differential term of the motor's PID controller

Use default parameters

Use the values for kp, ki and kd implemented in Robotinos firmware. These default values are also used if you set kp=ki=kd=255.

Reset on start

Initialize the Actual position with 0 at program start

 

Velocity control of each motor is performed by a PID controller

 

picontroller_equation

 

The parameters are:

 

Kp

Ki = 1/Tn

Kd

 

From the values set in the dialog the controller parameters are calculated as:

 

Kp= kp / 2

Ki= ki / 1024

Kd= kd / 2

 

Default values are

kp = 25

ki = 25

kd = 25
