—This paper presents the trajectory tracking control of a two-link planar robot manipulator using MSC Adams and MATLAB co-simulation which enables the innovative virtual prototyping of the systems without any mathematical expressions. Firstly, the tracking control performance of the planar manipulator is investigated using the Sliding Mode Control (SMC) controller and the Proportional Integral Derivative (PID) controller in terms of the performance analysis. As a result, the SMC demonstrates effective control performances compared to the PID controller according to the required trajectory, set ...Daha fazlası

In this study, topology optimization of a jet engine bracket which was proposed from GE Aviation challenge for improving the brackets is presented using finite element analysis (FEA). The minimum mass, maximum equivalent stress and first natural frequency are selected for the objective functions to topology optimization. Then, topology optimization procedure is implemented according to the identified boundary conditions and objective functions. Finally, the manufacturing model is obtained and compared with the original model according to the maximum equivalent stress, mass reduction and first ...Daha fazlası

This research is aimed at developing a multi-body simulation model and balancing control of a single-wheeled inverted pendulum. A virtual prototype of the system has been built by using Adams software and it is simulated in both Matlab and Adams software together. The Adams model has two inputs (disturbance and control) and two outputs (pendulum angle and wheel position). Proportional-integral-derivative (PID) controller is designed and applied for balancing control and simulation of pendulum angle. The modelling and control results show that the Proportional-integral-derivative (PID) controll ...Daha fazlası
In this study, a tuner-based Proportional-Integral-Derivative controller is proposed to actively control a smart beam. In numerical simulation environment, the performance of the tuner-based PID and a positive position feedback controller in damping the forced vibrations of a smart beam using a piezoelectric actuator are investigated. The finite element method is used to numerically model the smart beam by exporting the state-space matrices that are characterized with regard to the active vibration control loop. Two types of vibration data with sine tones are comprised in order to stimulate be ...Daha fazlası

This paper presents the design of a sliding mode controller (SMC) for trajectory tracking problem for a two-link planar robot manipulator. A virtual prototype of the manipulator has been built by using Adams software. Also, the controller works is achieved in Matlab/Simulink software. The system is simulated in both Matlab and Adams software together which is called co-simulation. The manipulator system has two inputs (torques of actuators) and four outputs (angle of 1st joint, angle of 2nd joint and x-y components of end effector position). The sliding mode controller (SMC) is designed with t ...Daha fazlası
In this study, modeling of a helicopter fuselage panel with active vibration control is carried out. In order to represent the helicopter body shell, a cabin panel clamped from four edges is designed. Piezoelectric patches are attached on the body according to the literature. The dynamic characteristics of the structure are obtained by finite element based modal analysis and exporting of state space matrices. The numerical model of the cabin panel is characterized with regard to active vibration control loop. Vibration data obtained from the helicopter operational tests is applied as a distort ...Daha fazlası

The stomatognathic system is a very complex structure that includes the temporomandibular joint, masticatory muscles, teeth, gingiva, tongue, and pharynx. In this structure, maximum bite force measurement has been an important field of study in the diagnosis and treatment of diseases caused by disorders related to chewing habits. Objectives: Since existing measurement systems are expensive and impractical, researchers are in search of better systems. In this study, a modular and low-cost system has been developed to measure the bite forces accurately. Materials and Methods: The sensor data rea ...Daha fazlası
