In this project, following a brief historical view on the control methods of DC motors and the first high power semiconductor devices, the mathematical models of different DC motors and buck converter are derived first. Using these equations, a high frequency buck converter is designed according to the model of the DC motor used in the experimental section. After that, using the designed converter,...
This article realizes a novel model of an internal combustion engine (ICE) based on its operating torque and speed for the purpose of designing new control strategies to optimize engine efficiency and performance in hybrid electric vehicles and power systems. The proposed model is developed such that it utilizes only a limited number of experimentally measured operating conditions of the internal...
In the present study we analyze the speed, acceleration, torque, boiler power during a complete phase of human walking and of the change of state: from sitting position to standing position. As a part of the experimentation methodology, we use artificial vision and with this we capture the points located in: hip, knee and ankle, these are states join by segments, to finally obtain the variation of...
Real-time simulation is proving very useful in simulating complex and expensive systems using the high performance multi-processors. It has many applications in the area of testing of controllers and protection systems under real-field like situations. In this project, an effort has been made to prepare a low-cost system to carry out real-time simulation in an educational laboratory setting. The system...
Permanent magnet synchronous motor (PMSM) servo system requires a high dynamic performance of speed. The control object of speed loop, which can be described using a two-order transfer function, is the PMSM regulated by current loop. PI controller is generally used in speed control, in which the performance improvement is limited by the strong coupling and nonlinearity of the system. In this paper,...
