Maybe I have an interesting example for this subject "FPGA & Motor Control":
There is an article available describing an example of a multi channel stepper motor control with a working secure stall detection algorithm by real time analysis of the motor electronic behavior performed by a xilinx spartan 3 FPGA:
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
