This paper presents modelling and simulation of DC-DC converter with matrix converter as its basic topology. The proposed converter performs the four quadrant chopper operation. This topology can perform many different converter functions. This DC-DC converter can be utilized in speed control of dc motor in electric automobiles and traction where supply is dc voltage. The simulation model was developed...
According to the working principle of certain artillery servo system, various component parts of artillery servo system are modeled using graphical modeling methods with MATLAB/ Simulink, and on this basis the general dynamic model of artillery servo system is established and simulated in the paper. The result shows that the model established can meet the characteristic requirements of the actual...
Servo punch press uses a servo motor to drive. It can set different stroke length and velocity according to different production requirements, and can always ensure the formation precision of the bottom dead center. It has the advantages of high efficiency, high precision and low noise, and it has become the development trend of punch press. The key point of the servo punch press development is its...
The switching power amplifier which is the plant of magnetic suspension control system is decisive of the stability of magnetic suspension control system, so the switching power amplifier was designed for magnetic suspension. At first, the simulation model of the switching power amplifier was proposed based on MATLAB/Simulink using power system block (PSB). The validity of the modeling method was...
Base on the characteristics of the shunt active power filter, we uses the power electronic devices of the MATLAB/Simulink to model the system, uses self-compiled S-function to carry out the ip-iq current detection algorithm. In order to compensate the harmonic currents generated by the non-linear load and the reactive power of the process, the PWM signal is generated to drive the IGBT by the way of...
The circuit and corresponding steady state vectors' relationship of single-phase PWM rectifier using IGBTs (insulated gate bipolar transistors) is analyzed, and the mathematic model and controller structure are presented, the PI regulators of the current and voltage loops are designed respectively. The method based on the Matlab/Simulink Blocks is used to carry out the simulation for the control system...
