D.Sivaraj,K.R.Radhakrishnan, A.Kandaswamy, J.Prithiviraj,S.Dinesh . Design of Automatic Steering Control and Adaptive Cruise Control of Smart Car. International Conference on VLSI, Communication & Instrumentation. ICVCI, 5 (None 2011), 12-16.
The objective of this work is to design and develop a multipurpose autonomous Smart car. The Smart car is a line follower which tracks a black line, on a white platform, with an array of infrared sensors. For efficient tracking, various control algorithms were implemented and the results were compared. The deviation from the track or line is treated as an error and the chosen algorithm serves to minimize this error. As the deviation is reduced, the traverse time, distance and power consumed in doing so is significantly reduced. For the steering to be more accurate and smooth the Proportional Integral and Derivative control mechanism was incorporated into the chosen algorithm. The entire system was designed in a closed loop fashion with the error value being fed back to the servo motors to make the necessary steering. Closed loop adaptive speed algorithm for DC motor helps in modifying the speed depending on the nature of the track. Tracking algorithm for servo steering and adaptive speed control algorithm for DC drive helps in optimizing the path trace, by prohibiting the rate of increase in error. Hence it is possible to bind both tracking as well as desired speed together. The performance of the control system has been greatly improved by proposed algorithm.
