This paper deals with the driver design for Brushless DC Motor (BLDCM) by quasi-sinusoidal voltage source inverter with voltage space vector pulse width modulation (VSVPWM) technology. Traditionally, BLDCM is driven by six-step inverter with digital Hall sensor feedback, and has the property of trapezoidal back EMF. However, this paper presents an approach to generate a quasi-sinusoidal voltage source...
In this study, we design the permanent magnet synchronous motor (PMSM) drive system using field programmable gate array (FPGA), and adopt variable structure control (VSC) to the current regulation. The system is first modeled with Matlab/Simulink, and the controllers in the system, including the speed PI control and current variable structure control, are hardware implemented by Verilog HDL code....
Although coreless motors have simple linear dynamic models with low complexity level regarding to the control of usual applications, frequently some kind of noise or vibration may arise if the coreless motor is operated in a general high gain control which is easy to deteriorate the performance. Besides, for most of the drive systems, the inner-loop current controllers are usually designed to be realized...
To develop a system with robustness, a servo motor motion controller by combining the two-degree-of-freedom (2DOF) system and sliding mode control (SMC) is proposed. The discussed motion is point-to-point control with trapezoid velocity profile. SMC is designed to guide the motor motion to follow a pre-defined trail, and the inner 2DOF scheme is used to compensate the deterioration due to the adoption...
This research focuses on the stepping motor drive system design based on an embedded system constructed by Field Programmable Gate Array (FPGA). It is known that the flexibility and programmable abilities have made the FPGA be widely used as controllers to the electrical machines and systems. Above all, the high density of recent developed chip results in many of the CPU cores can be embedded into...
Proportional-Integral-Derivative (PID) controllers are universal control structure and have widely used in automation systems, they are usually implemented either in hardware using analog components or in software using computer-based systems. In this work, we focused our works on building a multi-channel PID controller by Field Programmable Gate Arrays (FPGAs). Combining FPGA with high speed multi-channel...
This paper proposes a dynamic output feedback controllers for variable structure systems. It is based on the concept of output feedback controllers, introduced by Zak and Hui (IEEE Trans. Automat. Control AC-38 (1993) 1509) and Kwan (IEEE Trans. Automat. Control AC-41 (1996) 1691) for matched uncertain variable structure systems in which the state is unavailable and no estimated state is required...
