In this library we are using the voltage as a substitute for the torque control, why is that and how does it work exactly? On this page. PID controller reads the motor velocity v, filters it to v f and sets the torque target (u q voltage or i q current) to the torque control loop in a such manner that it reaches and maintains the target velocity v d, set by the user. Voltage mode - voltage; DC current mode - dc_current; FOC current mode - foc_current; In short voltage control mode is the simplest approximation of the motor torque control and it so basic that can be run on any motor+driver+mcu combination out there. Support for true FOC control - foc_current torque control - see in docs; New current sense alignment procedure #422 - see in docs. This value can later be used to control estimated torque of the motor and/or limit the estimated Arduino Simple Field Oriented Control (FOC) library . On this page. . By measuring the phase currents this torque control algorithm ensures that these voltages generate the appropriate currents and magnetic force in the motor rotor with exactly 90 degree offset from its permanent magnetic field, which guarantees maximal torque, this is called Simple FOC library gives you the choice of using 3 different torque control strategies: Voltage mode - voltage; DC current mode - dc_current; FOC current mode - foc_current. This means that the torque is proportional to the current and since the current is proportional to the voltage then torque is proportional to the voltage as well. The solutions that can be found on-line are almost exclusively very specific for certain hardware configuration and the microcontroller architecture used. Torque control loop. Simple FOC library gives you the choice of using 3 different torque control strategies: Voltage mode - voltage; DC current mode - dc_current; FOC current mode - foc_current. 5 Motion control parameters . This torque control approach allows you to run the BLDC motor as it is simple DC motor, where you set the target voltage U q to be set to the motor and the FOC algorithm calculates the necessary phase voltages u a,u b and u c for smooth operation. 基于电压的力矩控制能够像直流电机那样控制直流无刷电机，即设置目标电压U q ，然后FOC算法计算出所需的相电压u a ，u b 和u c 达到顺滑控制效果。 To go from the torque control using voltage to the torque control using current you just need to change the motor. PI controller theory; Position motion control; Motion control implementation v1. Simple FOC library implements 3 motion control loops: Torque control using voltage; Velocity motion control; Position/angle control And if it is any of the current torque control modes (FOC or DC current) or voltage mode with provided phase resistance, the angle motion control will be setting the target current i q to the torque controller: One of the reasons for this is the apparent complexity of writing the BLDC driving algorithms, Field oriented control (FOC) being an example of one of the most efficient ones. Torque control through voltage is the most basic torque control type, and it provides you an abstraction of the BLDC motor so that you can control Simple FOC library gives you the choice of using 3 different torque control strategies: Voltage mode - voltage; DC current mode - dc_current; FOC current mode - foc_current.
