Design Case (40mm Annular Control Board) This application design simplifies and optimizes the sensorless control algorithm for Brushless Direct Current (BLDC) motors, which is typically implemented by Digital Signal Controllers (DSC) or high-end 16/32-bit microcontrollers. It achieves complete control functionality on the New Tang enhanced 1T 8051 core microcontroller, highlighting the overall cost-performance ratio of … Read more
1. Choose the appropriate megger: If the rated operating voltage of the motor being tested is 380 volts, then we can select a 500V megger. 2. Place the megger flat, perform a short circuit test by shorting the two probes, and if the pointer approaches 0 while cranking the handle, it indicates good condition. 3. … Read more
1. Introduction to PID Control The PID (Proportional-Integral-Derivative) controller is the most classic feedback control algorithm in industrial control. It generates the control quantity through a linear combination of the proportional (Proportional), integral (Integral), and derivative (Derivative) parts of the error signal, achieving precise control of the system. Mathematical Model of PID Controller: 2. Case … Read more
Abstract: In the wheeled category of the Indonesian Wheeled Soccer Robot Competition (KRSBI), participating robots must be able to complete designated tasks, one of which is to chase and catch the ball. Omnidirectionality is one of the methods used for navigation in mobile robot applications that require all-around movement. Since this movement is designed to … Read more
