Trajectory-Free Control of Lower-Limb Exoskeletons Through Underactuated Total Energy Shaping
Kinematic control approaches for exoskeletons replicate normative joint kinematics associated with one specific task and user at a time, which makes it difficult to adjust to continuously-varying activities during gait training.

Using a Second Order Sigma-Delta Control to Improve the Performance of Metal-Oxide Gas Sensors [PDF]
Controls of surface potential have been proposed to accelerate the time response of MOX gas sensors. These controls use temperature modulations and a feedback loop based on first-order sigma-delta modulators to keep constant the surface potential ...

Modeling and Control of a Flexible Structure Incorporating Inertial Slip-Stick Actuators [PDF]
Shape and vibration control of a linear flexible structure by means of a new type of inertial slip-stick actuator are investigated. A nonlinear model representing the interaction between the structure and a six-degree-of-freedom Stewart platform system ...

Investigation of Multi-Input Multi-Output Robust Control Methods to Handle Parametric Uncertainties in Autopilot Design. [PDF]
Some level of uncertainty is unavoidable in acquiring the mass, geometry parameters and stability derivatives of an aerial vehicle. In certain instances tiny perturbations of these could potentially cause considerable variations in flight characteristics.

Roller coaster loop shapes revisited [PDF]
The original paper In 'Rollercoaster loop shapes', (Pendrill 2005 Phys. Educ. 40 517) the author started from the observation that although textbook loops are often circular, real rollercoaster loops are not. In this paper the mathematical description of various possible loop shapes, as well as their riding properties was discussed and also how a study

Adaptive Feedforward Cancellation (AFC) is commonly used to counteract periodic disturbances in mechatronic systems in order to enhance the control performance. So far, AFC algorithms either use no or positive damping.

H∞ Loop Shaping Robust Control For Tractor-semitrailer
The tractor-semitrailer model is general described and analyzed in road reference coordinate system. The lateral error of look-ahead distance has been chosen as nominal plant and a robust controller using H∞ loop-shaping procedure is designed which can ...

Casimir-Based Control Beyond the Dissipation Obstacle
A prevailing trend in the stabilization of port-Hamiltonian systems is the assumption that the plant and the controller are both passive. In the standard approach of control by interconnection based on the generation of Casimir functions, this assumption
