(DES) and Stability Management Control (SMC) (see figure). DES is an aircraft-mounted, high-speed processor that estimates the amount and type of distortion present and its effect on the engine. It uses high-response pressure measurements at the engine face to calculate indicators of the type and extent of distortion in real time. Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology that improves a vehicle's stability by detecting and reducing loss of traction (). When ESC detects loss of steering control, it automatically applies the brakes to help "steer" the vehicle where the driver intends to go.
If the computer detects a loss of steering wheel control or traction, the computer can reduce the engine power and/or engage the brakes to try and retain control of the vehicle. There are many names for electronic stability control, such as vehicle stability control (VSC) and dynamic stability control (DSC), but they all perform similar functions/5(). The position of the centre of gravity (CG). As a rule of thumb, the further forward (towards the nose) the CG, the more stable the aircraft with respect to pitching. However, far-forward CG positions make the aircraft difficult to control, and in fact the aircraft becomes increasingly nose heavy at lower airspeeds, e.g. during landing. The.

Performance. The objective of the High Stability Engine Control (HISTEC) program is to design, develop, and flight-demonstrate an advanced, integrated engine control system that uses measurement-based estimates of distortion to enhance engine stability.
The resulting distortion tolerant control reduces the requiredCited by: 8. developed for the High Stability Engine Control (HISTEC) program, and described in this paper, builds upon the distortion estimation approach of ADECS.
Through the use of a small number of engine-face pressure measurements, a more accurate estimate of the File Size: KB. The distortion tolerant control approach developed for the High Stability Engine Control (HISTEC) uses a small number of engine-face pressure measurements to accurately estimate the actual distortion present.
From this pressure-based distortion estimate, an onboard stability audit requests a time-varying stall margin Size: KB. the NASA High Stability Engine Control (HISTEC) program. 3 Distortion estimation is accomplished with a limited number of high-response static pressure measurements at the engine face and a frequency-based reduction algorithm.
The algorithm, known as the distortion estimation system (DES), predicts the loss of engine stability margin as a result of inlet distortion. Courtland D. Perkins and Robert E.
Hage are the authors of Airplane Performance, Stability and Control, published by by: ?It is well written with a good balance between mathematical rigger and physically insightful discussions. The book provides a good broad coverage of dynamics, stability and control of power systems covering all the major issues such as voltage stability, angular stability, frequency stability and control, /5(7).
The production engine control software was modified to incorporate the stability management features of HISTEC. This software was implemented within the existing engine control laws.
The IDEEC software is designed to allow easy updates on the flight- line to engine control schedules Cited by: Power System Stability And Control was published by McGraw-Hill Education in and is available as a paperback.
Key Features: The book is littered with multiple examples and illustrations in order to provide a pragmatic review of various concepts.
Power System Stability And Control is a part of the EPRI Power Engineering Series/5(74). see that the stability limit is what prevents the use of a very high controller gain to improve the control performance of the controlled variable.
Therefore, a thorough understanding of the stability of dynamic systems is essential, because it provides important relationships among process dynamics, controller tuning, and achievable Size: 7MB.
For a control system the input is the desired value, and the output is the actual value (See Figure ). Figure – SISO control system A good example is a cruise control system for an automobile. The user inputs a desired value, say 65 mph. Usually one does not type this in.

- Hydro-mechanical Size: 1MB. Abstract. This chapter surveys lean combustion techniques in internal combustion (IC) engines. The chapter begins by providing a brief review of the fundamentals of theoretical combustion and ideal combustion emissions.
Next, the effects of lean combustion in conventional and advanced spark-ignited IC engines are explored. Generalized dynamics control is a new concept, and is the scientific study of motion, force, and energy, which combines vehicle dynamics control (VDC) and energy-management system control.
Moreover, the structure optimization and generalized dynamics control can be divided into five parts.
The AIAA Education Series publishes books that are adopted for classroom use in many of the top undergraduate and graduate engineering programs around the world. These important texts are also referred to on a daily basis by aeronautics and astronautics professionals who want to expand their knowledge and expertise.
