Where to begin with digital control
The discussion on where to begin with digital control is an ongoing and popular thread. The thread has 49 replies from group members offering advice on what is important in digital control of power electronics
Another discussion covering a very specific issue is on handling slip-strike problems. Slip strike is what happens where the system output gets “stuck” and then suddenly moves. This typically happens in mechanical or hydraulic systems where the friction coefficient falls as movement begins. A relatively simple solution is to use a high derivative gain to reduce the effect. Other solutions include linearising the system to allow higher controller gains and higher bandwidth.
Choosing the control processor
The discussion on choosing the processor for digital control is also still popular. This covers which is the best micro controller or processor for digital control of power electronics. This is an ongoing and recurring theme as more people use digital control for their power electronics. Other subjects in the thread include
- analogue to digital converter choice
- aperture time
- settling time and
- how to design a digital loop compensator
Numeric precision and the effect of limited PWM timer bit limits are also mentioned.
