DC Motor control - Moving axis back and forth

[JZaulich]

Dear all,

I'm currently (trying) to design a control system for a servomotor.

I'm using a cRIO 9082, NI 9514 C-module, a Kollmorgen AKD servo drive and a Kollmorgen servomotor.

My main objective is to make the DC motor rotate from +15 deg to -15 deg and with variable frequencies.

I've verified the functionality of my system by using the "Axis straight line"-example, that comes with LabVIEW.

How do i get started making a more sophisticated movement pattern?

I've modelled the DC engine in MatLAB using a PID control. Can i do anything similar in LabVIEW?

See the attached image for the behaviour pattern i want to accomplish.

Thanks in advance.

Best regards,

JZaulich.

Hi JZaulich

You will need to use the NI Control Design and Simulation module to perform simulation and model of different systems.

If you install this toolkit there is a good example called "DC Motor Cascade Speed Control" that can show you how to model the DC motor and control it (both speed and current". There is also examples for servo control.
