Full text of "Pilot-Induced Oscillation Research: Status at the End of the Century". Flight test experience with pilot-induced-oscillation suppression filters Digital flight control systems are popular for their flexibility, reliability, and power; however, their use sometimes results in deficient handling qualities, including pilot-induced oscillation (PIO), which can require extensive redesign of the control system. When redesign is not immediately possible, temporary solutions, such as the .

The focus of this paper is to suppress the pilot-induced oscillation caused by both rate limiting and pure time delay by using the 𝐿 1 adaptive controller.

The effects of rate limiting and other system nonlinearities are considered to be the main factors that result in the occurrence of PIOs [ 3 – 5. 1. Introduction. Actuator position/rate-limit is an important issue in the design of flight control systems since it is one of the main causes of PIO and is listed in the Category II PIO which are mainly characterized by nonlinearity of actuator.Taking a look back at the history of aircraft, some fatal accidents caused by actuator rate-limit were witnessed, such as the crashes of YF in.

Such a phenomenon has led to significant research. Pilot-induced oscillations, as defined by MIL-HDBKA, are sustained or uncontrollable oscillations resulting from efforts of the pilot to control the aircraft and occurs when the pilot of an aircraft inadvertently commands an often increasing series of corrections in opposite directions, each an attempt to cover the aircraft's reaction to the previous input with an over correction in the.

is the Pilot Induced Oscillation (PIO). Military Standard Flying Qualities of Piloted Aircraft (MIL-STD A) [1] defines PIO to be “sustained or uncontrollable oscillations resulting from efforts of the pilot to control the aircraft”.

It usually occurs when the pilot is involved in a highly demanding.glider as they attempt to stop the oscillations from occurring in the first place. Pilot-Induced Oscillations (PIOs) The instability of a glider’s attitude that arises when the pilot fails to recognize the lag time inherent in controlling the glider is known as a pilot-induced oscillation (PIO).

An investigation of pilot-induced oscillation suppression (PIOS) filters was performed using the USAF/Flight Dynamics Laboratory variable stability NT aircraft, modified and operated by Calspan. This program examined the effects of PIOS filtering on the longitudinal flying qualities of fighter aircraft during the visual approach and landing task.
