This work presents the use of differential evolution (DE) for tuning a proportional-integral-derivative (PID) controller, linear quadratic regulator (LQR) with an integral action for aircraft pitch control. An optimisation problem for the two controllers are presented to optimise percentage of overshoot, settling time and steady state error while the weighted sum technique is applied. The design variables for the PID controller are control gains while for the LQR controller are the Q and R matrices. Various integral control gain values are employed for the LQR controller leading to a LQR with an integral action controller. The performance of the optimal controllers is investigated based on the single step and multiple steps response while some disturbance is also added. The results showed that PID controller is efficient for response speed while the optimum LQR with integral action controller is efficient for steady state error elimination. Both of the optimum controllers are robust and can handle disturbance rejection.
