ABSTRACT
Unmanned electric vehicles for autonomous driving are coming up especially for short-range drives as well as for special applications. This chapter presents an internet of things (IoT)-based extensive motor control for an unmanned electric vehicle (UEV) for different ranges of speed. The main aim of this chapter is controlling and monitoring of DC motor-based drives for unmanned electrical vehicles with a focus on the popular IoT protocol, Message Queuing Telemetry Transport (MQTT). MQTT is secure with friendly end user-based lossless and bi-directional connection support. Speed control for the DC motor is realized using a speed estimator and controller reducing speed error and giving a wider range of speed control. Another challenge in the case of an unmanned electric vehicle is collision avoidance and it is brought about using an intelligent control scheme supported by the IoT platform. Direction control is usually done via a servo-based drive which efficiently controls the UEV direction. The vehicle contains an unmanned vehicle control unit (UVCU) which will accept speed reference, steering angle with configuration commands, and the output for the same will be obtained via closed-loop control. The drive has a lower power requirement with improved control accuracy than the conventional closed loop-controller for UEV application.
