In modern spark ignited engines the throttle is controlled by the electronic control unit (ECU) which gives the ECU direct control of the air flow and thereby the engine torque. This puts high demands on the speed and accuracy of the controller that positions the throttle plate. The throttle control problem is complicated by two strong nonlinear effects, friction and limphome torque. This paper...

A disturbance accommodating controller (DAC) to reject wind speed perturbations is applied on a 5MW wind turbine mounted on a tension leg platform (TLP). Multi-blade coordinate (MBC) transformation is used to address the periodicity of the floating wind turbine system. A method to apply DAC after applying MBC transformation is developed and several implementation options are presented. Simulati...

The present work investigates a fault detection problem using gain-scheduled filter for discrete-time Linear Parameter Varying systems. We assume that the scheduling parameter cannot be directly measured but, instead, it is estimated. On one hand, this assumption imposes challenge should perform properly even when an inexact on other, avoids burden associated with design of complex estimation p...
