Control problems with time-lag. II

LSTM can Solve Hard Long Time Lag Problems

Standard recurrent nets cannot deal with long minimal time lags between relevant signals. Several recent NIPS papers propose alternative methods. We rst show: problems used to promote various previous algorithms can be solved more quickly by random weight guessing than by the proposed algorithms. We then use LSTM, our own recent algorithm, to solve a hard problem that can neither be quickly sol...

Lag time for children with brain tumours.

variable structure finite time guidance law with autopilot lag

in this paper, the problem of finite time stabilization for guidance system is investigated and a novel nonlinear guidance law against maneuvering targets is proposed based on the principles of parallel navigation. the proposed law is developed using two variable structure control techniques. by applying finite time integral sliding mode and combining it with terminal sliding mode, a new guidan...

Vibrational Control of Nonlinear Time Lag Systems with Bounded Delay: Averaging Theory, Stabilizability

This paper develops the theory of vibrational control Of "lhJear time Systems with arbitrarily large but bounded delay. theory for fast Oscillating, differential delay equations is presented and then applied to vibrational control. conditions B1p given which ensure the e*ne ot parametric vibrations that stabilize nonlinear time lag systems. Transient behavior is also discussed. Illustrative exa...

Problems of Anticoagulant Control—II, Which Test?

"It is a sad reflection on the limitations of clinical trials that 20 years after the introduction of oral anti-coagulants their place in the long term management of coronary artery disease is still disputed". It is more of a reflection on the limitations of the tests used to control anticoagulants. For example, after the publication of the most recent M.R.C. report on the use of anticoagulants...
