Missile Longitudinal Dynamics Control Design Using Pole Placement and LQR Methods

In high-maneuvering missile systems, with severe restrictions on actuator energy requirements, it is desirable to achieve the required performance least actuation effort. Linear Quadratic Regulator (LQR) has been in literature for long and proven it’s mettle as an optimal controller many benign aerospace applications industrial where response times of plant, most cases, are seen be greater than 10 seconds. It can observed that LQR control methodology not explored enough tactical requirement very fast airframe desired, typically order milliseconds. present research, applicability method one such agile critically explored. research work, longitudinal dynamic model flying at high angle attack regime established solution proposed bring out demanding energy. A novel scheme presented further optimise effort, which essential this class systems space constraints, by iteratively computing magnitude state weighing matrix Q cost R. Pole placement design techniques, though extensively used industry because ease implementation results, do address optimality system performance. Hence, a comparative study carried verify results against pole technique based controller. The efficacy over techniques successfully minimum paper. Futuristic maneuvering, constraints stand benefit incorporating
