On-Off Decentralized Control of Flexible Structures

Journal of Dynamic Systems, Measurement, and Control, 1991
A new near minimum fuel method for on-off decentralized control of flexible structures is introduced. Fuel minimization is achieved by turning on actuators when local velocities are in the neighborhood of a maximum and when local displacements are in the neighborhood of a minimum. Maximum velocity and minimum displacement neighborhoods at each actuator

A versatile electronic on-off controller

Journal of Physics E: Scientific Instruments, 1968
A description is given of an electronic on-off controller which permits of the selection of a wide range of on-off ratios as well as total cycle periods. The equipment will provide ratios from 0% `on' to 100% `on' in 1% incremental steps as well as three cycle periods. Reproducibility is better than 0·05%.

Analytical methods for thermostatic on-off controls

Building Services Engineering Research and Technology, 1980
Traditionally, automatic control theory has mainly been concerned with the behaviour of linear controllers, where the controller output is some continuous function of the error signal. These use combinations of Proportional, Integral and Derivative actions.

Fast and Accurate Pressure Control using On-Off Valves

International Journal of Fluid Power, 2005
Pneumatic cylinders and pneumatic muscles are lightweight, clean and multifunctional actuators, requiring pressureregulating valves for positioning. To use them in mobile applications commercial pressure-regulating valves are quite heavy and rather slow.

Control of on-off intermittency by slow parametric modulation

Physical Review E, 2004
We study on-off intermittent behavior in two coupled double-well Duffing oscillators with stochastic driving and demonstrate that, by using slow harmonic modulation applied to an accessible system parameter, the intermittent attractors can be completely eliminated. The influence of noise is also investigated.

Fluctuation-controlled transient below the on - off intermittency transition

Journal of Physics A: Mathematical and General, 1997
On - off intermittency is an ubiliquitous phenomenon observed beyond the instability of a particular chaotic motion. The system below the instability reveals a typical transient chaos. It is found that near the instability point the inverse characteristic first passage time satisfies the scaling law with the transverse Lyapunov exponent (TLE) , and

Other On/Off Control Case Studies

2012
Chapters 5 and 6 illustrate that the BOXES methodology works very well in prolonging the duration of motion of a freely hinged pole that is attached to a constantly moving cart driven by a theoretically instantly reversible motor. The algorithm reads the state variables and issues one of two possible control signals connected to the motor control ...

On-Off Control With Periodic Sensing Device

Journal of Fluids Engineering, 1958
Abstract The paper describes the effectiveness of PD-type control function for the on-off control system with a periodic sensing device. When the system is subject to steady random disturbance, provided that the disturbance is varying rather slowly compared to the time constant of the controlled plant, the properly chosen PD control ...

Dynamic-control problems with on/off cells [neurons]

Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003
In this paper, we study the dynamics of neurons and discuss how the neurons encode and decode both temporal and spatio-temporal signals. Dynamical properties (bifurcation, limit cycles, etc.) have been analyzed in an appropriate phase plane, whereas for the encoding and decoding scheme we have used a wavelet-based approach.
