Actuator controller What to use?

AI Thread Summary
An automatic egg turner is being developed for an old incubator, requiring an actuator to control a cradle movement of 45 degrees over 1-2 minutes, followed by a 4-hour pause before reversing the action. The user seeks advice on suitable PID controllers, as they have minimal experience with them. The actuator being considered is capable of handling the weight of the incubator setup, which totals approximately 120 kg but will only need to manage half that due to balance. The design also includes a feature to temporarily halt the movement for egg setting and restart the cycle with a button press. Assistance in selecting the right controller for this application is requested.

Hi Guy's I am building an Automatic egg turner for an old incubator .I wish to use an actuator and I need a way to control it .The egg turner is basically a set of stacked cradles that moves 45 degrees through 90 degrees and back again ,this action will need to be controlled so the actuator push's the cradles for a set amount of time slowly to reach a 45 degree angle over approx 1-2 minutes and stop ,sit there for 4 hours and then reverse the procedure (polarity) back through 90 degrees to the opposite 45 degree angle and once again sit for 4 hours and repeat this cycle continuously for about 4 months .I would also need to be able to temporarily halt this action and have the cradle sit in a horizontal position so more eggs can be set and at a push of a button restart the cycle .Having minimal experience with pid controllers I am at a total loss as to what to purchase so I hoped I may get help here ? This is the actuator I am looking at purchasing http://www.motiondynamics.com.au/linear-actuator-100mm-stroke-5mm-speed-5000n.html The incubator will hold 1350 eggs ,that's about 95 kg + cradle so it would weigh about 120 kg all up but would only need to push and pull half that weight due to balance ,the actuator is probably an over kill but better to be stronger than just strong enough .Many thanks in advance for your time

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
