Monte Carlo Based Detection of Parameter Correlation in Simulation Models

Maxwell Points of Dynamical Control Systems Based on Vertical Rolling Disc—Numerical Solutions

“…Based on the MP definition described earlier, if the end points do converge, we can take the end point for a Maxwell point. Formally, the optimisation task is then defined as (22), also with the constraints (20) and (21).…”

“…Using numerical approaches to solve different nonlinear tasks was proven useful in [20,21]. In Section 2 we describe a vertical rolling disc, including the derivation of differential kinematics and dynamics.…”

“…Find the second trajectory Now we need to find h * 20 for a second trajectory, which is different from h * 10 and drives the system towards the same point q M , as shown in Figure 3. We can formulate our constrained minimisation problem as (19) with constraints (20) and (21). The equality constraint ( 20) is meant to satisfy the same functional (9) for both trajectories.…”

Contactless Fault Detection of a DC Motor Direction of Rotation Using Its Stray Magnetic Field

“…Before the application of the diagnostic technique in a large-scale manufacturing process, we need to acquire the reference image of the magnetic flux difference vector b re f according to Equation (1).…”

“…With smaller motors, however, the magnetic field is physically changing at a smaller scale, which makes the measurement sensitive to the background, noise, size, and exact positioning of the sensing element and requires much more precise measurement techniques. This applies to the whole dynamics of the motor and makes all measurements, control, and parameter analysis harder [1,2]. It follows that these kinds of external diagnosis methods would be beneficial over classical invasive approaches for diagnosis and fault detection, which require disassembly or dedicated internal sensors.…”
