This paper has introduced a design of digital speed control system of permanent magnet brushless DC motor based on MCS-80C196KC.The system use Direct Back-EMF to detect rotor position, and combined with three-start technology to expand the speed control range. Application of Double Closed Loop PID control method to overcome the limitations of conventional control methods, which provide a new way for...
The principle of capacitive PWM control circuit was analyzed in this paper, the soft-switching solution was applied in the switching devices, and the practical main circuit topology was given. On the load current to achieve a frequency tracking, To make the power factor of the inverter close to or equal to a quasi-resonant state, the Frequency of the load current was tracked. The phase compensation...
In this paper, the road information collection systems and processing algorithms of video signal was researched based on vision sensor, the processor of Smart car used MC9S12XS128, the hardware of Sampling system using OV7620 digital camera; The key of software part is the turn of double-array storage and processing technology, which made the Acquisition system has higher efficiency, more in line...
In this paper, Six DC Motor-Driven was designed for the Smart Car Competition of University Students, after a comparative analysis of the experiment, receiving the advantages and disadvantages of the six methods. Finally, a driven approach with strong drive capability, small size, and stable performance is established, and it can be widely used in the occasions of high-power DC Motor-Driven less than...
As the traditional ways of MPPT suffers from some dissatisfaction, this paper presents a kind of Fuzzy Support Vector Machines (FSVM) for the prediction and simulation of the voltage of the maximum power output in PV module. The measured data of meteorological light intensity was used to simulate and analyze shows that Compared with BP Neural Network, the model of FSVM achieved the minimization principle...
