Assessment of Performance for Single Loop Control Systems
نویسندگان
چکیده
Assessment of performance in tracking set-point changes for single loop systems is presented. In contrast to the works that used stochastic performances, the current assessment uses a deterministic performance measure, i.e. the integration of absolute tracking errors (abbr. IAE). A benchmark system that has an open loop transfer function (abbr. OLTF) comprised of one LHP zero, one integrator, and dead time is established. This benchmark system is used to provide a goal of performance that the existing system can practically achieve. For assessing an existing control system, the performance of the system in terms of IAE is computed and an index that indicates the extent of achievement toward this benchmark system is computed. Evaluation of control based on this index can then be made. The model required in computing the aforementioned performance index can be obtained from an auto-tuning procedure.
