The paper deals with three robust control systems that may be regarded as a part of the model‐following control (MFC) family. The systems are easy‐to‐synthesize control structures, thus offering an alternative to the low‐robust single‐loop PID system, to the relatively difficult‐to‐synthesize internal‐model control structures, or to complex adaptive systems. A basic comparative theoretical and computational analysis of properties exhibited by the presented control structures is given. Also, recommendations as to practical implementation are provided. The solutions presented in the paper have found some application, e.g. in force/position control for an industrial robotic manipulator, temperature control of electro‐heated furnaces with highly varying parameters, and oxide content control in a steam boiler. Owing to the interesting robustness properties displayed by MFC strict requirements on quality of controlled processes that are both strongly nonlinear and time variant have been met.
