The output from a linear control system into the controlled process may be in the form of a directly variable signal, such as a valve that may be 0 or 100 % open or anywhere in between.

He continued writing and in 1962 published the book "'Non Linear Control Systems Analysis "', also giving a paper on the topic to the annual conference of FISITA, the International Federation of Automotive Engineering Societies.

Books with a simple table of contents or index may be considered interactive due to the non-linear control mechanism in the medium, but are usually considered non-interactive since the majority of the user experience is non-interactive reading.

Dijkstra's thesis was that departures from linear control flow were clearer if allowed only in disciplined higher-level structures such as the structured programming movement, the title of his 1972 book, coauthored with C . A . R . Hoare and Ole-Johan Dahl.

Sometimes this is not feasible and so, after calculating the current required corrective signal, a linear control system may repeatedly switch an actuator, such as a pump, motor or heater, fully on and then fully off again, regulating the duty cycle using pulse-width modulation.

Dr . Kazerooni has also been conducting research on human performance in coordinated haptic-visual virtual environments under several contracts from NASA . Other research interests are biomimetic design, haptics, non-linear control systems, embedded systems, networked control systems, power regeneration, monopropellant and portable energy generation methods for mobile platforms.

To augment the company's standalone phono preamplifiers, standalone line stage preamplifiers were introduced next, known as Linear Control Centers or LCC . One of the innovative features of the LCC was a bypass switch that permitted the user to select the use of an internal amplification module or straight into the potentiometer for volume control.

Variable geometry intakes, such as those on Concorde, vary the ramp angle to focus the series of oblique shock waves onto the intake lip, control of which is accomplished by complex non-linear control laws using the ramp void pressure ( the pressure of the air in the gap between the two ramps ) as a control input.

In the case of VHS, a linear control track at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks.
