The quantitative performance indicators of Physical Unclonable Functions (PUFs)-Randomness, Steadiness, Correctness, Diffuseness and Uniqueness-are strictly defined and applied to the evaluation of 45 arbiter PUFs on Virtex-5 FPGAs. The indicators effectively reflect the characteristics of PUFs ranging from 0 to 1 with 1 being the highest performance. The indicators enable the easy measurement and...
In this paper, we design a new controller for power-assisted wheelchairs. Conventional power-assist controllers only focus on the amplification of the human input force using torque sensor. Our proposed controller does not use a torque sensor but an electromyogram sensor to estimate the driver's intention. We also use a disturbance observer to compensate for the lack of propelling torque information...
A new traction control which utilizes the maximum transmissible torque estimation (MTTE) scheme to execute the anti-slip control of electric vehicles is proposed in this study. Since the function of embedded knowledge mechanism, the chassis velocity and information about tire-road conditions is unnecessary. A closed-loop observer with disturbance estimation performance is employed to enhance the steering...
Motor's fast torque response is one of the advantages of electric vehicles (EVs), and the advanced anti-skid control is included in this advantage. Simulation results show that the feedback gain of wheel velocity control can be high enough to suppress the serious skid, if the actuator delay is small enough. The dynamics of wheel can be changed with this control, and the driven wheel's inertia can...
