The two-port network theory for describing the characteristics of the haptic interface is presented; the four-channel bilateral control architecture is introduced, and two control methods named position-error-based control and direct force reflection control (PEBC & DFRC) are also presented. Two main problems caused by the coupling between position and force information for transparency improvement of the haptic interface are also be discussed and a Model-Based Force-Position Compensation Strategy to enhance the transparency of the haptic interface is proposed. By embedding the compensation unit into the DFRC architecture, the Haptic Interface could be controlled with precise position and high-fidelity force feedback.

Cockpit Design

With the advent of integrated electronics displays in advanced cockpit design, the role of dynamic mockups is becoming increasingly important. The human factors researcher can now evalute dynamic computer generated formats and real-time interactive control methods in preliminary crew station design phases. This ability to prescreen candidate display formats prior to evaluation in high fidelity simulators is very cost effective. Instead of being limited to conventional static capability, the rapid advances in micro-chip technology now allow more sophisticated research at the mockup level. This paper describes the design of a dynamic mockup which incorporates state-of-the-art microprocessors, graphic systems, and voice capability.

We consider fast high-fidelity quantum control by using a shortcut to adiabaticity (STA) technique and optimal control theory (OCT). Three specific examples, including expansion of cold atoms from the harmonic trap, atomic transport by moving harmonic trap, and spin dynamics in the presence of dissipation, are explicitly detailed. Using OCT as a qualitative guide, we demonstrate how STA protocols designed from inverse engineering method can approach with very high precision optimal solutions built about physical constraints, by a proper choice of the interpolation function and with a very reduced number of adjustable parameters.
