In this paper, a robust tracking control method for automatic take-off and trajectory tracking of a quadrotor helicopter is presented. The designed controller includes two parts: a position controller and an attitude controller. The attitude controller is designed by using the sliding mode control (SMC) method to track the desired pitch and roll angles, which are the output of position controll...

In this paper, the effect of the Intake Valve Deactivation (IVDA) on engine performance is investigated in detail. Based on an optimization platform with Genetic Algorithm (GA) and engine thermodynamic model, the characteristics of the engine volumetric efficiency and pumping loss were studied under the cam-drive, Single Intake Valve (SIV) and Dual Intake Valves (DIV) operating modes, and the e...

a new output structure for class e power amplifier (pa) is proposed in this paper. a series lc resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. this resonator causes low impedance at the second harmonic. the output circuit is designed to shape the switch voltage of the class e amplifier and lower the voltage stress of the transistor. t...

ATS (Automatic Transfer Switch) merupakan sistem untuk menghubungkan beban dengan dua sumber tenaga listrik (sumber utama dan cadangan) yang terpisah menjaga ketersediaan aliran daya menuju beban. Pembangkit Listrik Tenaga Surya (PLTS) saat ini sudah sangat sering digunakan di masyarakat. Dalam hal memprioritaskan energi dari PLTS dijadikan sangatlah baik, akan tetapi menghasilkan bergantung ke...

We have developed an intelligent single switch scanning interface and wheelchair navigation assistance system, called ISSWN, to improve driving safety, comfort, and efficiency for individuals who rely on single switch scanning as a control method. ISSWN combines a standard powered wheelchair with a laser rangefinder, a single switch scanning interface and a computer. It provides the user with c...
