چکیده

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

Design a Guidance Law Considering Approximation of Missile Control Loop Dynamics Using Adaptive Back-Stepping Theory

In this paper, a new guidance law is designed to improve the performance of a homing missiles guidance system in terminal phase. For this purpose first of all, the two dimensions equations of motion are formulated, then the approximation dynamic of missile control loop is added to these equations which are nonlinear whit unmatched uncertainty. Then, a new adaptive back-stepping method is develo...

Pole Placement Design Technique 8.2 State Feedback and Pole Placement

has the desired specifications. The main role of state feedback control is to stabilize a given system so that all closed-loop eigenvalues are placed in the left half of the complex plane. The following theorem gives a condition under which is possible to place system poles in the desired locations. Theorem 8.1 Assuming that the pair is controllable, there exists a feedback matrix such that the...

Feedback Synchronization using pole-Placement Control

Synchronization in chaotic systems has become an active area of research since the pioneering work of Pecora and Carroll. Most existing works, however, rely on a passive approach: A coupling between chaotic systems is necessary for their mutual synchronization. We describe here a feedback approach for synchronizing chaotic systems that is applicable in high dimensions. We show how two chaotic s...

2-DOF block pole placement control application to: have-dash-II missile

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 diffe...
