Abstract
The fuel efficiency, maximum torque and power, and pollutant emissions of internal combustion engines have improved rather than conventional crankshaft system. These improvements are the result of replacing the crankshaft with a camless actuation technology. Soft landing, tracking the desired trajectory, valve seating in a low velocity and having a small time for valve opening and closing are some of the main conflicting objectives in camless engines. Due to the nonlinear model of the system, feedback linearization control is presented for dealing with the system challenges in this paper. Moreover, to optimize the system response, the concept of feedback linearization control is incorporated into the linear quadratic tracker and makes the proposed structure named FLQT. The simulation results indicate the optimal feedback linearization controller has a good performance in the realization of desired goals of the system.
