Hello everybody
I have bought an actuator (LINAK PLC LA12)
Datasheet is here :
http://www.linak-us.com/pdf/english/la12_plc_eng.pdf
STRIPPED ACTUATOR:
I have removed the circuit that regulates the piston. All that is left is
the mechanical system between the permanent magnet DC-motor and the piston.
MICROCONTROLLER (Keil MCB167-NET)
I have a microcontroller that is able to generate PWM-signals. The
microcontroller also has an A/D-port, which I will use to gain
feedback-information that is necessary to regulate the position of the
piston.
INTERFACE:
Between the stripped actuator and the microcontroller, there will be an
interface. This interface will consist of an amplifier and a H-bridge. The
H-bridge will control the spin-direction of the motor based on a PWM-signal
from the microcontroller. I have to build this circuit.
SOFTWARE FOR MICROCONTROLLER:
I need to make a software algorithm that regulates the position of the
piston according to a desired, pre-defined position P. The software sets up
the right PWM-signal and sends it to the interface. The software receives
information about the state of the actuator and corrects errors by adjusting
the PWM-signal. The correction continues until the desired position has been
acquired.
How do I make the algorithm? And how do I make the interface?
Thanks,
Jakob
