為了提高直接轉矩控制(DTC)系統定子磁鏈估計精度,降低電流、電壓測量的隨機誤差,提出了一種基于擴展卡爾曼濾波(EKF)實現異步電機轉子位置和速度估計的方法。擴展卡爾曼濾波器是建立在基于旋轉坐標系下由定子電流、電壓、轉子轉速和其它電機參量所構成的電機模型上,將定子電流、定子磁鏈、轉速和轉子角位置作為狀態變量,定子電壓為輸入變量,定子電流為輸出變量,通過對磁鏈和轉速的閉環控制提高定子磁鏈的估計精度,實現了異步電機的無速度傳感器直接轉矩控制策略,仿真結果驗證了該方法的可行性,提高了直接轉矩的控制性能。 Abstract: In order to improve the Direct Torque Control(DTC) system of stator flux estimation accuracy and reduce the current, voltage measurement of random error, a novel method to estimate the speed and rotor position of asynchronous motor based on extended Kalman filter was introduced. EKF was based on d-p axis motor and other motor parameters (state vector: stator current, stator flux linkage, rotor angular speed and position; input: stator voltage; output: staror current). EKF was designed for stator flux and rotor speed estimation in close-loop control. It can improve the estimated accuracy of stator flux. It is possible to estimate the speed and rotor position and implement asynchronous motor drives without position and speed sensors. The simulation results show it is efficient and improves the control performance.

一個數據訪問層Torque3.1的生成器的源代碼,在我的DWF框架就提供了對他的支持。torque本身與hibernate類似,但使用起來更簡單,特別他的生成器可以直接通過掃描數據庫來生成相應的數據庫訪問層。

This code proposes genetic algorithm (GA) to optimize the point-to-point trajectory planning for a 3-link robot arm. The objective function for the proposed GA is to minimizing traveling time and space, while not exceeding a maximum pre-defined torque, without collision with any obstacle in the robot workspace.

該步進電機驅動器又稱為EasyDriver,EasyDriver能夠為兩級步進電機提供大約每相750mA(兩極一共1.5A)的驅動。它默認設置為8步細分模式(所以如果你的電機是每圈200步,你使用EasyDriver時默認為每圈1600步),更多細分模式可以通過將MS1或MS2兩個接腳接地進行設置。這是一種基于Allegro A3967驅動芯片的細分斷路器。對于此設計的完整規格,請查閱A3967的參數表。它的最大每相電流從150mA到750mA。可以采用的最大驅動電壓大概是30V,其中包括板載5V的調壓器,所以只需要一個電源。質優價廉,這玩意兒只要十幾美元,比你自己制作電路板更便宜。步進電機驅動器設計特色:· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
