Crane merupakan alat pendukung pada bidang industri, dalam penerapannya beban yang ditanggung oleh crane beragam, maka diperlukan sebuah sistem dalam mengatur kecepatan kerja crane untuk menyesuaikan jenis barang yang ditanggung. Dalam penelitian ini dilakukan perancangan prototype overhead crane dengan penggerak motor DC magnet permanen CSD80A1-A yang di dioperasikan oleh buck converter. Pengaturan kecepatan putar motor DC magnet permanen sebagai penggerak  prototype overhead crane dilakukan dengan memvariasikan nilai duty cycle pada buck converter. Prototype overhead crane ini dilakukan pengujian dengan variasi tidak dibebani dan dibebani sebesar 5 kg. Berdasarkan hasil pengukuran buck converter, nilai output terendah terjadi pada gerakan forward transversal tidak dibebani dengan duty cycle 60% yang menghasilkan daya keluaran 7,74 watt, kecepatan putar 76,53 rpm, dan torsi 0,96 Nm. Nilai output tertinggi terjadi pada gerakan forward longitudinal dibebani 5 kg dengan duty cycle 90%, yang menghasilkan daya keluaran 24,79 watt, kecepatan putar 80,59 rpm, dan torsi 2,93 Nm.

This paper analyzes the effect of stable behaviors when amplitude, phase of sine voltage compensation signal are added in the system, reveals that the dynamical behaviors mechanism that sine voltage compensation signal changes feedback voltage-mode controlled buck converter lies in changing the duty cycle without impacting the system stable error via analyzing the change of period multiplier in Monodromy matrix and conditions of period bifurcation, and finally achieves stabilization control for bifurcation and chaotic behaviors. The simulation and experimental results prove the correctness of the theoretical analysis.

Pulse width modulation (PWM) is used to generate pulses with variable duty cycle rate. The rapid rising and falling edges of PWM signal minimises the switching transition time and the associated switching losses. This paper presents a DC motor speed controller system using PWM technique. The PWM duty cycle is used to vary the speed of the motor by controlling the motor terminal voltage.The motor voltage and revolutions per minutes (RPM) obtained at different duty cycle rates. As the duty cycle increases, more voltage is applied to the motor. This contributes to the stronger magnetic flux inside the armature windings and the increasethe RPM. The characteristics and performance of the DC motor speed control system was investigated. In this paper, a PIC microcontroller and a DC-DC buck converter are employed in the DC motor speed controller system circuit. The microcontroller provides flexibility to the circuit by incorporating two push button switches in order to increase and to decrease the duty cycle rate. The characteristics and performance of the motor speed controller system using microcontroller was examined at different duty cycle rate ranging from 19% to 99%.
