In this paper, a simple method is developed for desiging a single loop PID contriller using a computer oriented algebraic approach which is based on general polynomial. Specifically, the proposed PID controller can approximately achieve an arbitrarily specified closed-loop response, which satisfies time domain specifications such as rising time, overshoot and settling time. The design technique is straightforward, and the paramaters of the PID controller are determined by solving a set of linear equations using the least squares method. It does not involve any trial and error proceduer, hence the difficulty of the conventional approach can be avoided.
