There are tried-and-true methods of tuning PID controllers, based on theory and years of experience, that I would not characterize as "guess and check". If the P, I, and D are tuned in the proper order, with the gain in each step being adjusted to obtain specific dynamic behaviors, a near-optimum solution can often be reached in only one or two passes.
