    Input shaping is a feedforward control technique for improving the settling time and positioning accuracy, while minimizing residual vibrations. Shaped command profiles are generated by convolving a sequence of impulses. To design an input shaping controller, estimates of the system natural frequency and damping ratio are required. However, real systems cannot be modeled exactly, making the robustness to modeling errors an important consideration. Many robust input shapers have been developed, but robust shapers typically have longer durations that slow the system response. This creates a compromise between shaper robustness and rise time. This paper analyses the compromise between shaper duration and robustness for several robust input shapers

    Experimental Investigation of Performance and Emission Parameters Changes on Diesel Engines using Anisole Additive
    (Trans Tech Publications Ltd, 2014) Baltacioglu, Mustafa Kaan; Aydin, Kadir; Yasar, Ergul; Arat, Huseyin Turan; Conker, Caglar; Burgac, Alper
    In this study, effect of anisole additive into the diesel fuel on performance and emission parameters of diesel engines was investigated. Instead of structural changes which are more difficult and expensive, development of fuel technologies is preferred to provide reduction on exhaust gas emissions which are harmful to environment and human health. Therefore, in this experimental study, anisole was used as additive into diesel fuel with the volumetric ratio of 1,5%, 3% and 5%. The performance characteristics and exhaust emissions of a four cylinder, four stroke, naturally aspirated, water cooled, direct injection compression ignition engine fueled with modified fuels were analyzed. Engine was subjected constant speed, full load conditions during tests. Engine power, torque, specific fuel consumption, carbon monoxide, nitrogen oxide and carbon dioxide emissions were measured and results were evaluated. Changes in performance parameters were negligible for all ratios of modified fuels except specific fuel consumption. Finally, while carbon monoxide gas emissions were increased with anisole additive, carbon dioxide and nitrogen oxide gas emissions were decreased.
