Here’s a recent brochure from Altera on Motor control solution in industrial space.
“While microcontrollers and DSP devices may be well suited to certain aspects of motor control systems, they lack flexibility to support motor control IP and interfaces in hard logic. With our Cyclone® III FPGA, you can integrate processors, digital logic interfaces, DSP functions, motor control IP and multiple Industrial Ethernet protocols into one device, reducing board size and complexity. Operating across industrial communication networks, motion control solutions with drive-controlled motors can be very energy efficient. Aside from saving power, this can also lead to net cost savings in the long run.”
It may be important to mention that this type of system architecture in industrial space – with industrial ethernet connection – is “smart-grid” ready, i.e. information is going in two direction : to the motor drive system for motor control and from the motor drive system for condition-monitoring purposes.
In that latter case, the motor drive system may become a “broadcaster” of useful information to the main control system if the Motor Control IP contains fault-detection and diagnosis algorithms that are running simulataneously with torque and speed control algorithms.
