2-DOF block pole placement control application to: have-dash-II missile
This work addresses control design for a specific missile model, but the method is incremental and application-specific.
The paper proposes a 2-DOF control law using block pole placement for multivariable servomechanism design and applies it to the HAVE DASH II missile, achieving improved transient response and robustness.
In a multivariable servomechanism design, it is required that the output vector tracks a certain reference vector while satisfying some desired transient specifications, for this purpose a 2DOF control law consisting of state feedback gain and feedforward scaling gain is proposed. The control law is designed using block pole placement technique by assigning a set of desired Block poles in different canonical forms. The resulting control is simulated for linearized model of the HAVE DASH II BTT missile, numerical results are analyzed and compared in terms of transient response, gain magnitude, performance robustness, stability robustness and tracking. The suitable structure for this case study is then selected.
