A phase lag controller is a type of controller used in control systems to improve the system's performance. It introduces a phase lag to the system's response, which can help reduce steady-state error.
Steady-state error refers to the difference between the desired output and the actual output of a control system when it has reached a stable operating condition. By introducing a phase lag, a phase lag controller can adjust the system's response to reduce this steady-state error.
While a phase lag controller can improve certain aspects of the system's response, such as reducing overshoot and improving transient response, the primary effect it has is on reducing steady-state error. It does this by modifying the phase relationship between the input and output signals, effectively adjusting the system's steady-state behavior.
Therefore, the correct answer is B: Reduction in steady state error.
