I need a professional PCB design that scales a 0-10VDC current signal to a 0-24VDC output, with a maximum of 5A. The main power supply for this project will be 24VDC. It's vital that the 0-10VDC input side is completely isolated from the output and the main power input side. Here are the specific requirements: Isolation: Basic isolation is needed between the input and output. Control System: An analog control system is expected for output management. Form Factor: The PCB should conform to a standard size, without the necessity for miniaturization or enlargement. This may be used to control the speed of a 24VDC motor or a brake or any DC appliance which has variable duty according to the voltage received. Ideal candidates for this project should have extensive experi...
...experienced Arduino programmer with expertise in Control Engineering to develop code to control a servo motor in either position or velocity mode at speeds ranging from 2 rotations per second to 1 rotation every 2 minutes. It's crucial that the speed control is stable so that rotation remains stable and smooth and controlled within 1% of the speed demand. This will involve creating a source code to read a quadrature encoder signal, to measure the phase current and control current, speed and position control loops using the SimpleFOC shield board. Control loop speed should be sufficient to meet the speed and position control required. The proposed hardware includes an Arduino Due with a SimpleFOC motor control board and a CubeMars GL60KV25 motor...
