Cam follower mechanisms are used for obtaining complex motion outputs at follower end with different profile curve inputs at cam end. The kinematic behaviour of follower establishes basic suitability of cam for a given application and it is decided by the cam profile curves, which is main input of cam follower system. In this paper synthetic curves, that are generated parametrically through a set...
Attitude and altitude control of quadrotor is investigated in this paper. Stable sliding surfaces are used for devising robust control for roll, pitch, yaw motion and altitude. Gao's power rate reaching law is used to devise proposed sliding mode controllers. The robustness of the controllers is verified in simulation. The method is validated in MATLAB simulation. The proposed controller is compared...
Modeling complex mechatronic systems containing parts such as mechanics, electronics and software is a major challenge for the engineering of automation production systems. As a result, many modeling languages as well as tools (e.g. petri nets or MATLAB/Simulink) and verification approaches (e.g. testing, simulation or formal verification) that focus on special challenges to model the mechatronic...
A semi-active control heave compensation system is proposed, according to the requirements of 6000m deep sea poly-metallic mining system. The heave compensation system is acted upon by interacting of dynamic vibration absorber with accumulator. Magneto-rheological damper is act upon actuator to take semi-active control of heave compensation system. The composition and principle of the heave compensation...
Passive rehabilitation robots are the auxiliary equipment which used to help patients recovering from diseases. In this paper, we addressed a lower limb 4-degree of freedom (4-DOF) model, proposed a lower limb rehabilitation mechanism. Based on MATLAB/Simulink software, analyze the displacement, speed and acceleration of fulcrums are analyzed. Experiment results verified that the simulation results...
It is always a hard work to optimize the parameters of auto disturbance rejection controller (ADRC) because of its too many parameters. An optimization method for designing the submarine course ADRC based on the Nonlinear Control Design (NCD) block set of Matlab was proposed. The chief algorithm of ADRC and characters of the NCD block set were referred in briefly too. It was pointed out that there...
Set up the mathematical model after the dimension was achieved, and then kinematics simulation analysis could be easily doing by using MATLAB\SIMULINK simulation platform. Parameters could be easily modified and the analytical solution could be got accurately, design time could be saved and the quality of the product could be improved. The results were saved in the workspace of MATLAB software, and...
This paper studied the physical properties of multilayered corrugated board, fully considering the air-flow of flute influence on its properties. Built up the theoretical model of pre-compressed multilayered corrugated board. Used MATLAB/Simulink software simulate theoretical model to determine the value of acceleration during impact. In a qualitative way the simulated results tend to coincide with...
