Implementing two DC motor speed control strategies

Abstract

While linear control techniques for dynamic systems have been widely tested, systems are not linear in practice. This means that controllers must be re-tuned to make them useful in an experimental setup. This article presents the tuning and re-tuning process for two control strategies: a PID and an algorithm based on the choice of overall transfer function controlling a DC permanent magnet motor. The algorithms’ performance is evaluated and some recommendations are made.
