Unmanned and autonomous systems require a great deal of human trust, especially in order to gain acceptance for high-risk mission applications. In the aerial domain, loss of vehicle control, crashing or leaving the safety of the designated range can present a hazard to human safety as well as property. This represents a key barrier in current safety review processes when considering an experime...

The feedforward path of an autopilot is designed for the longitudinal dynamics of a tactical missile. A linear parameter-varying model is used to synthesize a self-scheduled control law based on a parameter-dependent Lyapunov function. The controller is evaluated on a nonlinear model of industrial complexity both under nominal conditions and parametric uncertainty. Tracking performance is signi...

As the technological capabilities of automated systems have increased, the use of unmanned aerial vehicles (UAVs) for traditionally exhausting and dangerous manned missions has become more feasible. The United States Army, Air Force, and Navy have released plans for the increased use of UAVs, but have only recently shown interest in the cyber security aspect of UAVs. As a result, current autopi...

Interception problems are often dealt with by separating guidance and autopilot design. Guidance law can be obtained using optimal control theory and autopilot design is performed on a linearized system. In this paper, we introduce a new approach that determines a global guidance and autopilot law, based on direct output feedback design. Application of this method to exoatmospheric interception...

Abstract: The paper addresses the design of an autopilot for small scale helicopters to let the vertical, lateral, longitudinal and yaw attitude dynamics to track aggressive references. The paper is mostly focused on robust control aspects of helicopters. In particular the distinguish feature of the control law proposed in the paper is the ability to deal with the presence of possible severe un...

We design a feedback control architecture for longitudinal flight of an aircraft. The multi-level architecture includes the flight control loop to govern the short term dynamics of the aircraft, and the autopilot to control the long term modes. Using H∞ performance and robustness criteria, the problem is cast as a non-convex and non-smooth optimization program. We present a non-convex bundle me...

this paper presents a gain scheduled autopilot for pitch channel of a flying vehicle. the selected method is based on polynomial fuzzy systems. the method does not involve linearization about operating point. first the polynomial fuzzy model of pitch channel of the flight body is derived. next, using polynomial fuzzy system methodology the controller is design such that the outputs of the nonli...

In this paper, the decision parts of a launch rocket—guidance law (GL) and autopilot—are discussed. In the controller design, the differential geometry and sliding mode control are employed. In addition to the individual GL and autopilot system, stability of the integrated guidance/autopilot (G/A) system are discussed. Finally, various simulations are demonstrated to examine the feasibility and...
