Title: A comparative analysis of tracking quality for cdm and pid control
Authors: Wojciech Giernacki
Abstract: A tracking quality of CDM and PID control in systems with SMPO (stable, minimum-phase, oscillatory) plant are presented and compared in this paper. Constraints of control signal amplitude and step type of disturbance were considered in simulation tests, where for the synthesis of PID controller Matlab 7.0/Simulink Response Optimization libraries were used. The synthesis of robust control system was conducted with the use of coefficient diagram method (CDM) algorithm. These two methods were compared on a benchmark of trajectory tracking. Comments of the results obtained for these methods are given. In all of simulation tests, a higher quality of tracking was obtained in CDM system.
