The method that was used in the study is a classic design method used by D. P. Atherton. The method has been shown to be successful by adding time-delay and parameter uncertainty to this classic design method. The controllers are obtained by the implementation of individual design steps for the phase-lead and phase-lag controller. The unit-step responses and Bode diagrams of the systems with controllers are plotted. Considering the results obtained, it is observed that the method gave successful results for a fractional order plant with time-delay and parameter uncertainty.}, publisher={Tokat Gaziosmanpasa University}
