Study on Switched Reluctance Motor Control System Based on DSP

Accord to the theory of micro-step control, this study is about a design of a four-phase switched reluctance motor based on DSP-driven control system. Firstly, the study is about the design of the hardware circuit, such as the power inverter and its drive, current detection, position detection and the system power supply. And then to build a switched reluctance motor control system, TMS320L2812...

Mitral Ball-Valve Prosthesis

REPLACEMENT of nonfunctioning valves is a significant recent advancement in the correction of cardiac valvular disease. The most widely used artificial device replacing the mitral valve is the Starr-Edwards ballvalve prosthesis.' Its effectiveness was shown in recent reports by the marked clinical improvement in properly selected patients.2 However, cardiologists and cardiac surgeons are faced ...

Permanent Magnetic Synchronous Motor Control System based on ADRC

Permanent magnetic synchronous motor (PMSM) is a strong coupling and non-linear system. In the PMSM speed-regulation system, PID controller is the conventional one, it is difficult to decide the parameters of PID. Moreover, the performance of PID controller is not very well in large disturbance. In the paper, the Active Disturbance Rejection Controller (ADRC) is applied to the PMSM speed-regula...

Dc Motor Control Based On Fuzzy Logic System

This paper presents an application of an adaptive fuzzy logic controller (AFLC) for a DC motor system with nonlinear friction. The developed AFLC ensures that: 1) the close-loop system is globally stable and 2) the tracking error converges to zero asymptotically and a cost function is minimized. The simulation results show that the proposed AFLC operates well and provides good quality of the co...
