-PID how to achieve through VHDL language, let's take a look at this file.

When PWM waveform is generated by FPGA, it can be realized only by using the internal resources of FPGA. One end of the digital comparator is connected with the set value output, and the other end is linearly increased by the counter output. When the count value of the linear counter is less than the set value, it outputs a low level, and when the counter is greater than the set value, it outputs a high level. Therefore, fuzzy influence. Rar]-VHDL fuzzy PID controller carries out fuzzy reasoning, and the reasoning result is directly output together with the empirical value. 【 a _ Real-time _ Adaptive _ PID _ Controller _ Step _ Motor. Rar]- The traditional PID controller is usually difficult to meet the requirements of multivariable, nonlinear and strong coupling stepping motor dynamic response and accurate speed regulation. Combining the advantages of traditional PID control, fuzzy control and genetic algorithm to adjust PID parameters, a real-time adaptive stepping motor PID controller based on fuzzy genetic algorithm is designed to give full play to the respective advantages of traditional control strategy and intelligent control strategy. The simulation results show that the real-time adaptive stepping motor PID [fuzzy _ PID _ control _ of _ stepping _ motor. Rar]- Abstract: Because of the nonlinear characteristics of stepping motor speed control system, the precision of simple fuzzy control and traditional PID control is not high, so a method of using fuzzy PID controller to control stepping motor speed control system is proposed, and the fuzzy PID controller is designed. In this paper, the mathematical model of stepping motor is established at first, and its transfer function is deduced according to the mathematical model. Then the structure of fuzzy PID controller is introduced and realized by verilog of [PID _ controller _ latest]. Tar.gz]-PID controller.
