Smart Car PWM control DC Motor In the automotive industry, we must not only control the operation of automobiles through the CAN bus, but also need a DC motor to control the speed of the automobile in the intelligent remote control automobile market: we can use PWM wave at ordinary times, hardware changes voltage and other methods to change the voltage value at both ends of the vehicle motor, and then adju

For DC, in the instant of the closed switch, the capacitor is connected to the positive electrode of the power supply, the positive charge is the majority, The negative charge on the plate connected to the anode of the power supply is the majority, and the electric potential of each point in the circuit is equal immediately. Therefore, the capacitor in the DC circuit can play a role in separating the

DC Motor Speed Regulation?for a given model, just modify the Controller part of the simulation purposes can be achieved, the previous code only proportional link, no integral and differential links, so need to increase these two links, here set kp=8 , Ki=1 , kd=60 , the resulting simulation waveform isIt can be seen that the acceleration and deceleration time is very short, rapid reaction, the overshoot is not small, the speed curve has a very low dev

Source: A ATMEGA128-based DC Motor lock-Dead programLet me tell you something about my hardware: a ATMEGA128 test board; a 80:1 variable speed motor with encoder, the output of the encoder is connected to the PD4 and PD5 pin of the microcontroller, and a motor drive circuit, the input of this circuit is: 24v power supply, two PWM signal input, The output is the positive and negative pole of the motor, to use the circuit to drive the motor, you must le

I. Preface When learning OpenGL, we found that many functions are global. In the previous chapters, we used to draw images in a window DC. How do we deal with drawing in multiple windows? There are a variety of online methods, one of which is used here. The wglmakecurrent function is used to switch between different windows, so that multiple windows can be simultaneously blurred. 2. Preparation Each window is bound to OpenGL through the following proc

I see a lot of screen interception articles on the Internet, I believe we have seen a lot. Every step of human progress is built on the basis of others, and what I am going to do today is to dynamically display a window on another window. The method is very simple, the core algorithm is to complete a window DC display to another window of the DC, in order to facilitate the reuse of code, I specifically put

The circuit is named after the "H-Bridge drive circuit" because its shape resembles the letter H. 4 transistors make up the 4 vertical legs of h, and the motor is the horizontal bar in H (Note: The figure is a schematic, not a complete circuit diagram, where the transistor's drive circuit is not drawn). The H-bridge motor dri
