Description: 介绍了一种闭环智能数控直流电流源的设计原理和实施方案，该方案采用自行设计制作的高精度电压源，利用单片机、PWM和运算放大器构成A/DD/A转换器来控制场效应管导通状态的原理，达到了输出恒流的目的。整个系统采用89C58单片机作为主控部件，将预置电流值数据送入D/A转换器，经硬件电路变换为恒定的直流输出，同时使用采样电阻将实际输出电流转换成电压送入A/D转换器，并将其反馈到单片机中构成闭环系统，进而实现预设值和实际值的比较，再通过调整D /A转换器输出的电压来改变场效应管的导通状态，减小了实际值与预设值之间的误差，实现了电流可预置、可步进调整、输出的电流信号可直接数字显示的功能。采用硬件闭环、软件闭环、软件实时积分、实时滤波的方法，锁定输出电流，从而实现了高精度恒流源的目的。此次所设计的电流源具有精度高、结构简单、工作稳定、操作方便、成本低廉、带负载能力强等优点-The scheme adapts high precision voltage source designed by ourselves Micro Control Unit (MCU) D/A converter and amplifier to control the transmitting state of field effect transistor which attains constant current. The system adapts MCU 89c52 as main control part the output current is transformed into the voltage by sample resistant and the voltage is sent to D/A converter and then sent to the MCU compared with the setting current. If there exist errors we should adapt D/A converter output and change the transmitting state of field effect transistor. The actual value is directed to the setting value. The direct current reaches the constant value. The closed loop control and PID arithmetic is used to realize high precision and wide range in the software design part. The intelligent current source realizes that the output current can be preset adjusted step by step and displayed in digit directly. Above functions are operated by keyboard within the current source. The stability of this

[Software Engineering] A_real-time_adaptive_PID_controller_step_motor

Description: 传统PID控制器通常难以满足多变量、非线性、强耦合的步进电机动态响应和精 确调速要求,结合传统PID控制和模糊控制及遗传算法(GA)整定PID参数的优点,设计基于 模糊遗传算法的实时自适应步进电动机PID控制器,充分发挥传统和智能控制策略各自的优 势。仿真结果表明,该实时自适应步进电动机PID控制器,具有很好的自适应能力和抗负载扰 动能力。在稳定性、动态速度响应诸方面均优于传统的PID控制器和模糊控制器,系统达到了 较高调速性能和控制精度。 -Traditional PID controller is often difficult to meet the multi-variable, nonlinear, strong coupling dynamics of stepping motor response and accurate speed control, combining the traditional PID control and fuzzy control and genetic algorithm (GA) 整 PID parameters set the advantages of the design based on fuzzy Adaptive genetic algorithm in PID controller, stepper motor, give full play to traditional and intelligent control their own advantages. Simulation results show that the real-time adaptive PID controller, stepper motor, has good adaptive ability and resistance to load disturbances. The stability of the dynamic speed response is superior to the traditional aspects of PID controller and fuzzy controller, the system reached a high speed performance and control precision.
