    PID Controller for PWM of a linear drive motor?

    I have linear drive motor that I drive with a PWM signal of frequency 1kHz. The minimum duty cycle for the linear motor to start moving without any load is 30 %. Now I am trying to design and tune a PID controller to control the position (ranges from 0 - 10000 counts). My difficulty in...

    Can someone help me please!!!? IRFZ44n MOSFET heats up driving TEC Peltier

    Hello everyone, I would really appreciate if you could help me Im making a mini fridge controller (PID), using a 4n25 optocoupler, an IRFZ44n Mosfet and a tec peltier I connect it to a 12v and 3 A and arduino 5v As soon as the arduino code is uploaded and I connect it, the mosfet starts to...

    Does a 3-phase phase-locked loop diagram possible for an AC to DC battery charger?

    Hi there, In order to achieve unity power factor control, the phase of the AC voltage needs to be obtained. The phase is obtained through a phase-locked loop (PLL). Take a look for single phase control structure of the PLL , For such similar way I want to mention some of 3-phase equations...

    Trying to control a motor speed with a PID circuit.

    Hi everyone! I'm Buse. I'm trying to control a motor speed for a personal project. You can find the schematic of the circuit I found on a book. This circuit works with only the PID parts contrcuted. My problem start when I add the other parts. For example, U1 opamp (top left) is supposed to...
