Mixed sensitivity control: a non-iterative approach por Galindo Orozco, René

“…The proposed MSC is based on the minimization of the most common closed-loop sensitivity functions in low frequencies and the free-parameters of the stabilizing-controllers solve an algebraic equation of restriction that assigns the same value to the infinity-norms of the sensitivity functions at low and high-frequencies, guaranteeing robust stability and robust performance. It is assumed that the plant state dimension is double the plant input dimension and that the linear time-invariant nominal plant has a stabilizable and detectable realization and is strongly stabilizable. …”

Detoxification of Aflatoxin-Contaminated Maize by Neutral Electrolyzed Oxidizing Water por Jardon Xicotencatl, Samantha, Díaz Torres, Roberto, Marroquín Cardona, Alicia Guadalupe, Villarreal Barajas, Tania, Méndez Albores, Abraham

“…Our results showed that, after the aflatoxin-contaminated maize containing 360 ng/g was soaked in NEW (60 mg/L available chlorine, pH 7.01) during 15 min at room temperature, the aflatoxin content did not decrease as confirmed by the immunoaffinity column and ultra performance liquid chromatography methods. Aflatoxin fluorescence strength of detoxified samples was similar to untreated samples. …”

Prony Method Estimation as a New Approach for Surge Comparison Testing in Turn Insulation Diagnostics for Three Phase Stator Windings por Trujillo Guajardo, Luis Alonso, Rodríguez Alfaro, Luis Humberto, Rodríguez Maldonado, Johnny, González Vázquez, Mario Alberto, Salinas Salinas, Fernando, Shih, Meng Yen

“…Then, a numerical simulation is used to define a simulated turn fault surge voltage signal, where its parameters can be obtained with Prony method estimation and compared with EAR to evaluate its performance. Lastly, recorded surge test signals from two tested motors are used to validate Prony method estimation application for surge test diagnostics, where twelve recorded surge signals for no-fault and fault conditions were analyzed. …”
