WebModule 6: Vehicle Lateral Control. This week, you will learn about how lateral vehicle control ensures that a fixed path through the environment is tracked accurately. You will see how to define geometry of the path following control problem and develop both a simple geometric control and a dynamic model predictive control approach. WebGPS RNAV systems can compute “track angle error” (TAE), the difference between the desired track and the actual track (Fig. 3). TAE is mathematically proportional to the rate of change of XTE, the important manual control variable. In principle, if TAE is available, the pilot would not have to
