ted to allow efficient ballistic missiles , the paper describes a recently developed ted estimation/guidance design paradigm n several innovative concepts that provides satisfactory homing performance against ly maneuvering targets. The new paradigm veloped and tested first by using a simplified constant speed interception scenario model. paper the integrated estimation/guidance m is validated ...

In traditional engagement model, there is only one single weapon or platform which resists to another single one, and the connections between members are few, so the complete and global information in engagement space can’t be utilized sufficiently, which directly results in traditional model is confronting with more and more disadvantages especially as the high-tech and information-tech are de...

The state dependent Riccati equation (SDRE) technique is a recently developed methodology for designing control laws and estimation algorithms for missile flight control. Although its potential is well recognized by control theory experts, the industry acceptance of the technique has been slow. The main reasons for this are: a) unlike linear control technology, the SDRE approach requires advanc...

The backstepping design method has been used to design the control system of the Bank-to-turn (BTT) missile, which depends on the designer’s personal experience and a large number of complicated iterative calculation, and needs to consume a lot of time throughout the design process. To solve this problem, a missile control system surrogate model is established by using Kriging meta-model. After...

The thin-layer Navier-Stokes equations are solved for two complete missile configurations on an IBM 3090-200 vectro-facility supercomputer. The conservation form of the three-dimensional equations, written in generalized coordinates, are finite differenced and solved on a body-fitted curvilinear grid system developed in conjunction with the flowfield solver. The numerical procedure is based on ...

An application of reinforcement learning to a differential game is presented. The reinforcement learning system uses a recently developed algorithm, the residual form of advantage learning. The game is a Markov decision process (MDP) with continuous states and nonlinear dynamics. The game consists of two players, a missile and a plane; the missile pursues the plane and the plane evades the miss...

During the last five years, Oerlikon Aerospace developed and implemented engineering processes. In this paper, we discuss the application of risk management to the re-engineering of operator console stations of a missile weapon system. We briefly describe the systems engineering process. Finally, twelve lessons learned are discussed. PROCESS DEVELOPMENT BACKGROUND Oerlikon Aerospace (OA) is the...

– A Roll Position demand (as well as Roll Position Control) missile autopilot design methodology for a class of guided missile, based on state feedback, Ackermann pole-placement and reduced order Das & Ghosal observer (DGO), is proposed. The open loop unstable model of the roll control (or roll position demand) autopilot has been stabilized by using pole placement and state feedback. The non-mi...

The Electronic Warfare Division, of the Avionics Laboratory at the Wright Research and Development Center (WRDC), WPAFB, has two in-house facilities which are used in the evaluation of conceptual infrared (IR) and electro-optical (EO) countermeasure techniques. The ftrst facility, called the Dynamic Infrared Missile Evaluator (DIME), is a 6-degree of freedom hardware-in-the-loop infrared (IR) m...
