Question is not formulated clearly. When you estimate models of different orders, System Identification Toolbox produces a chart showing the tradeoff between model order and accuracy. If you want the highest accuracy, select the highest order. Most often, you would want to pick the lowest order that still gives you good accuracy. After then, tune the controller using pidtune or pidtool functions
