Апстракт
Wide usage of relay feedback test for controller tuning naturally leads to numerous investigations for its improvement and extension of its application to the various objects and control strategies. Present paper contains testing possibilities for application relay feedback test to the already decoupled two input two output system. The aim is to protect system from influence of the interaction during procedure of tuning of PID controller or its shorter variants. Survey has been supported by simulations in order to prove efficiency of presented approach on the two examples of systems. The results confirm that relay feedback test can be applied simultaneously to the all loops of the previously decoupled multivariable system.
