The design of an idle speed controller for automotive engines is considered. A hybrid nonlinear model of the engine is presented. Based on suitable (nonlinear) change of variables, the idle speed control design problem can satisfactorily be addressed via LTI techniques. Specifically, the design problem has been formalized as a finite dimensional(More)

OBJECTIVE to evaluate the results from surgery with computer-assisted navigation in cases of total knee arthroplasty. METHOD a total of 196 patients who underwent total knee arthroplasty with computer-assisted navigation were evaluated. The extension and flexion spaces (gaps) were evaluated during the operation and the alignment after the operation was(More)
PURPOSE To verify the influence that increased femoral anteversion (FA) has on patients with recurrent patellar instability (RPI) treated by anteromedialization tibial tubercle osteotomy (TTO) combined with medial patellofemoral ligament reconstruction (MPFLR) and to present the midterm outcomes of these patients. METHODS From January 2008 to August 2013,(More)
PURPOSE To compare the outside-in transtibial lateral and medial approaches for posterior cruciate ligament (PCL) reconstruction regarding the guidewires and popliteal artery integrity. METHODS Twenty-two human cadaveric knees were used. A PCL tibial aimer was arthroscopically placed within the PCL footprint through the anteromedial portal for the medial(More)
— In this paper we present an idle speed controller for automotive GDI engines. The idle speed control problem is formalized as a robust constrained optimal control problem for a hybrid model of the GDI engine. The cost to be minimized is fuel consumption. A sub-optimal robust controller is obtained by using the Command Governor methodology for a(More)
