Modern and Classical Pitch Control for Yak54

The present paper discusses the trade-offs between classical and modern controllers by designing a pitch hold autopilot for of yak54. Autopilots decreases the workload of pilots, making the flight more reliable and efficient. A pitch controller is initially designed using a classical technique, where root locus and Bode plots are studied to design a suitable feedback controller. Linear quadratic integrator (LQI), with a stable inner loop, is also synthesized to control the pitch attitude of yak54 using tools available in MATLAB. The classical and modern controllers are compared, and trade-offs of the designed controllers are discussed, supported with simulation results obtained via MATLAB.
