    i've been trying to do this project and have tried many times. but i dont know what im gettign wrong.
    i have a system/transfer function in simulink as a PD controller. a rule base in fuzzy logic (mamdani).
    and i need the output to have less than 10% overshoot and the lowest rise time.
    what sort of surface should i be trying for this? i've been trying all day but i always get overshoot at a ridiculous number (eg 300%)

    i dont know if this is enough information..
