    Hi,
    I need to design a temperature controller for my application. I want to start with a basic on-off controller and would like to also work out a PID controller for it (later).
    It would be great if somebody could share some good design resource for this / share a link where there may be some pointers available on how to proceed.

    I have worked out a basic circuit with an opamp and a power mosfet that implements the on-off circuit, but I am not convinced that I have it all right. I need some more info!!

    Thnx

    If you can post up a schematic of your circuit, perhaps we can help...

    Is it tougher to design a controller where the controlled variable is AC? I have the option of DC as well as AC in my application and want to know which is the better way.
