The purpose of the study was to develop an optimized joystick control interface for electric powered wheelchairs and thus provide safe and effective control of electric powered wheelchairs to people with severe physical disabilities. The interface enables clinicians to tune joystick parameters for each individual subject through selecting templates ...

An Optimally Controlled Respirator
IEEE Transactions on Biomedical Engineering, 1971An optimally controlled respirator was developed. It has three main features: 1) ventilation is controlled by the patient's metabolic rate from continuously measured C0 2 output, 2) physiologic dead space approximated as a linear function of tidal volume is used to estimate alveolar ventilation, and 3) respiratory rate is computed to minimize ...

Distributed Optimization for Control
Annual Review of Control, Robotics, and Autonomous Systems, 2018Advances in wired and wireless technology have necessitated the development of theory, models, and tools to cope with the new challenges posed by large-scale control and optimization problems over networks. The classical optimization methodology works under the premise that all problem data are available to a central entity (a computing agent or node).

There are several optimal control problems that can be naturally cast in a set-theoretic framework and for which set-theoretic techniques provide efficient tools. Although by far non-exhaustive, this chapter considers several cases and discusses several solutions.

Optimal controllers are fragile
Proceedings of the 2003 American Control Conference, 2003., 2004Optimal controllers are structurally unstable. The instability is intrinsic because of constrained optimization. This kind of instability is sometimes identified with "fragility" in the control literature. The fragility is related to hidden degeneracies in the polynomials and matrices of the optimized systems, and may detected by looking for certain ...

LINEARISATION BY OPTIMAL CONTROL
IFAC Proceedings Volumes, 1983Abstract Numerical approximations for the solutions of some nonlinear models are considered. The linearisation is realized by means of a perturbation term introduced in the right hand side of the equation and the solution is obtained via an optimal control problem.

For discrete-time control-affine systems on an infinite interval, an analytical solution of the greedy optimal control problem is presented. The "greedy" formulation of the optimal control problem calls for minimization of the instantaneous cost function, rather than the cumulative one, as in the conventional optimal control.
