Performance assessment and redesign of PI controllers with pulse excitations

In this paper a methodology is presented to assess the performance of PI controllers from closed-loop response data for pulse setpoint signal. Here a previously published technique is extended to evaluate and redesign single-input single-output (SISO) control loops for single and double pulses. The paper describes a system identification procedure for continuous-time transfer function models and demonstrates how it can be used for control performance assessment and controller redesign.
