At present, there are different kinds of individual battery test systems. In the area of traditional individual battery test systems, these systems are too big to carry and the price are too high. According to solving these problems, a new hardware design which is based on FPGA of Lithium Individual Cell Test System is creatively put forward in this paper. This kind of test system offers a way more...
At present, the technique of dual redundancy CAN-bus is mainly implemented by software, so that it has the disadvantages of low reliability and bad real-time performance. Built on the error handling rule in CAN specification version 2.0, a hardware redundancy management unit is creatively put forward in this paper. Based on FPGA, a kind of customized Dual Redundancy CAN-bus Controller (DRCC) is designed...
In order to solve the problem of precise control of non-linearity system, a digital fuzzy-PID controller is designed by combining the advantages of fuzzy inference and PID controller based on FPGA. First, the model of the controller is established on the platform of Simulink. Simulation result shows that the controller exhibits a good transient response and a stable control action despite of the divergent...
A system module of reactive power measurement is proposed on the basis of analyzing the mathematic model in this paper. A FFT intelligence property (IP) core is designed to estimate the amplitude and phase of harmonic. Two multipliers and a subtraction also are designed to calculate reactive power. Transposing circuit is applied to fix the data in order to reduce error of the system. An adder module...
