Flatness-Based Tracking of an Electromechanical Variable Valve Timing Actuator With Disturbance Observer Feedforward Compensation

R.R. Chladny, C.R. Koch

IEEE Transactions on Control Systems Technology > 2008 > 16 > 4 > 652 - 663

A comprehensive control strategy for an automotive solenoid variable valve timing actuator is presented that addresses the issues of feedback sensors, soft seating or landing control, disturbance rejection and feedforward design. In particular, the motion control of the engine exhaust valve actuator subject to large cycle-to-cycle gas force variations is successfully demonstrated in simulation and...

Flatness-Based Tracking of an Electromechanical VVT Actuator with Magnetic Flux Sensor

R.R. Chladny, C.R. Koch

IEEE International Symposium on Intelligent Control > 663 - 1668

2006 IEEE Conference on Computer Aided Control System Design, 2006 IEEE International Conference on Control Applications, 2006 IEEE International Symposium on Intelligent Control

A flatness-based end controller of an automotive solenoid valve has been demonstrated in both simulation and on an actuator test-bench. The simulation model provides an accurate representation of the real system and allows for the development of control strategies. The simulation results are contrasted with those of an actuator test-bench equipped with 42 volt automotive solenoid valves and a pressure...

A magnetic flux-based position sensor for control of an electromechanical VVT actuator

R.R. Chladny, C.R. Koch

2006 American Control Conference > 6 pp.

2006 American Control Conference

A promising method for enhancing automotive internal combustion engine efficiency uses solenoid actuators to directly control gas exchange valves. Mitigation of valve seating velocities is challenging due to phenomena such as magnetic saturation and pressure disturbances. Production implementation of an electromagnetic valvetrain will require the development of cost effective yet accurate sensors...
