## 3. In a closed loop system, the process to be controlled is an integrating process with transfer function $$\frac{1}{{2{\text{s}}}}.$$ The controller proposed to be used in an integral controller with transfer function $$\frac{1}{{{{\text{T}}_1}{\text{s}}}}.$$ When a step change in set point is applied to such a closed loop system, the controlled variable will exhibit
