Digitalization has already affected every segment of the industry and especially manufacturing. Based on market requires that are more specific and faster than ever, there is a need to use some of the online platform packages called Cloud Manufacturing (CM). CM operate through the digital data then here comes the expression CAD models or in particular STL files that are currently adequate for Additive Technologies (AT). On the other hand, there is a rapid increase in the measurement aspects via non-contact forms (3D scanners) where their data are stored in various digital formats: IGES, OBJ, PLY, etc.). Those formats can …

Designing A Controller Via Simulated Annealing, Zemerart Asani, Selvet Rexhepi
UBT International Conference
With Proportional-Integral-Derivative (PID) controllers being widely used in industry for optimum solutions. Optimization of the PID controller is an important problem in Control Engineering. Therefore, in this paper work we have implemented Simulated Annealing to tune the controller parameters. Optimizing the controller parameters on the basis of the Simulated Annealing algorithm, based on criteria defined using an objective function, allows us to find optimal solutions for the controller parameters that give us minimum error. In terms of performance, the PID controller designed with Simulated Annealing gives us great results with regard to the rise time, settling time, overshoot and steady-state …

“New” Subjects In Mechatronics Management Education, Peter Kopacek
UBT International Conference
Process – and manufacturing automation as well as robotics are currently one of the fast growing fields in automation. Advanced process control, cyber-physical systems, industry 4.0 and “advanced robots” are no longer a headline. They are in realization. As a consequence of these developments new social, ethical and human questions appear. Therefore this contribution is a first report about the continuous “modernization” of the Mechatronics Management BSc and MSc programs which are successful running at UBT. Both programs were developed in the framework of two TEMPUS projects from an international consortium from 2006 to 2009. Since that time new “buzzwords” …

Optimal Control Of Dc Motors Using Pso Algorithm For Tuning Pid Controller, Arnisa Myrtellari, Petrika Marango, Margarita Gjonaj
UBT International Conference
The DC motors are widely used in the mechanisms that require control of speed. Different speed can be obtained by changing the field voltage and the armature voltage. The classic PID controllers are widely used in industrial process for speed control. But they aren’t suitable for high performance cases, because of the low robustness of PID controller. So many researchers have been studying various new control techniques in order to improve the system performance and tuning PID controllers. This paper presents particle swarm optimization (PSO) method for determining the optimal PID controller parameters to find the optimal parameters of DC …

Noise Reduction In Quadcopter Accelerometer And Gyroscope Measurements Based On Kalman Filter, Bertan Karahoda, Xhemajl Mehmeti, Uran Cabra
UBT International Conference
The Accelerometer and Gyroscope modules used for measuring the orientation of the quadcopter usually generate noisy signals which directly affect the control strategies. The high speed motors used in quadcopters cause high noise levels which makes the real time control almost impossible. In this work the Kalman filter is applied to the noisy measurements obtained from accelerometer and gyroscope modules. The measurements are conducted for two cases: Motors stopped, and Motors activated at high speed. The Kalman filtering is applied separately for each measurement and the obtained results show noticeable improvement in noise level for two cases. The joint implementation …
