The Eulerian-Lagrangian approach was used to simulate the liquid-solid two-phase flow, and Reynolds time-averaging equations were solved to simulate the fluid phase, while the stochastic trajectory model was adopted to obtain properties of particles.
For verification, the program was applied to an experimental articulated piston of a certain type diesel engine (D×S=95×115mm) to compute the piston tilt angle and lateral motion trajectory.

Actual motion trajectory of one actuator was used as the ideal target for another to track,based on the time-varying nonlinear characteristic of actual hydraulic system,variable structure control approach was adapted for reducing synchronous motion error of two actuators.
Motion control is an important branch of automatic control, and it has got extensive application because of its precise control for motion track and moving velocity.
Based on the blur image synthetic technique, wavelet transform was applied to enhance and abate noise of blur micro-resonator motion images, while the traditional image processing method is used to extract the motion track features, and finally the natural parameter of micro-resonator was acquired as important reference for MEMS design.
P-type open-closed-loop iterative learning control (ILC) is not based on model parameters and has advantages in both open-loop and closed-loop ILC; so this paper proposes a complex robot gait trajectory tracking.
The simulation results indicate that the dynamical sliding-mode controller can not only track the given trajectory correctly but also reduce the chattering of sliding-mode control system considerably.
To precisely implement the force control of robot manipulators in an unknown environment, a control strategy based on fuzzy prediction of the reference trajectory in the impedance model is developed.
The elliptical trajectory of the driving tip is formed by exciting the longitudinal and bending vibration with phase difference, which generates thrust force and normal force, respectively.
Compliant manipulation requires the robot to follow a motion trajectory and to exert a force profile while making compliant contact with a dynamic environment.
The lubricant viscosity, which is assumed to be an effective function of the temperature of the lubricating layer, is adjusted at each step of the calculation of the crank pin's motion trajectory.
We study the case in which by change of an external parameter the stable motion (trajectory) becomes unstable and is replaced by a set of new trajectories (bifurcation).
These results demonstrate that fairly chaotic neural control perturbations have very little influence on the resulting motion trajectory, at least in the present example.
The parallelism of saw guide motion locus against the blade is one of the main items in the testing of the geometric precision of the whole woodworking band sawing-machine.
