DESAIN DAN KONSTRUKSI SISTEM KONTROL POSISI PADA PANEL SURYA DENGAN MENGGUNAKAN SMART PERIPHERAL CONTROLLER(SPC)-STEPPER MOTOR DAN PC-LINK USBER ABSTRAK Telah didesain dan dirancang sistem pengontrol posisi panel surya terhadap sinar datang cahaya matahari dengan menggunakan SPC-Stepper Motor dan PC-Link USBer, sehingga diperoleh posisi panel surya yang selalu tegak lurus arah sinar datang cahaya matahari. Pengontrolan bidang penampang (panel surya) dilakukan menggunakan motor-stepper yang diprogram dengan bahasa pemrograman assembly. Data yang digunakan sebagai input diperoleh dengan pengukuran sudut datang sinar matahari, sehingga posisi panel surya selalu tegak lurus terhadap sinar datang cahaya matahari. Sistem pengontrol dapat bekerja pada step minimum 1 step (2,8°), dengan interval mulai dari 8 step sampai 50 step (pukul 07:00 sampai pukul 18:00). Kata kunci: Motor stepper, panel surya, system control   CONTROL SYSTEM DESIGN AND CONSTRUCTIONS  OF SOLAR PANEL BY USING SMART PERIPHERAL CONTROLLER (SPC)-STEPPER MOTOR AND PC-LINK USBER ABSTRACT Solar panel position control system to coming ray directions of solar light have been designed and constructed by using SPC-Stepper Motor and PC-Link USBer, so we had solar panel positions that always been rectangular to coming ray directions of solar light. Cross section area of solar panel controlled by using motor-stepper which programmed with assembly programming. Data used as input found by measuring of coming solar ray angles, so solar panel position always be rectangular to coming rays of solar lights. Contolled system could been done at minimum step of 1 steps (2.80),  the interval is 8 step to 50 step (at 07:00 to 18:00). Keywords: Stepper motor, solar panel, control system

he proposed FPGA and SRAM peristaltic intelligent dispensing machine control system design based on the can not only quickly, accurate, intelligent control of dispensing glue, to achieve precise control of the liquid flow rate, can also be used for other work in the intermittent condition of instrument. In addition, through the use of single-chip microcomputer to control the step motor, to achieve the control purpose of peristaltic pump. The user input the motor rotation speed and rotation direction of rotation of the step number, at the same time flexibly, can obtain from the MCU according to its input data generated by a series of control signal, the motor rotate normally. In the dispensing process, through the external interrupt, can be changed at any time of peristaltic pump working mode. This system realizes the machine position control, speed control, interpolation calculation of real-time task, and construct the concept of digital dispenser system. Practice has proved that this system overcomes the dispensing accuracy of traditional time pressure dispensing machine is not high, prone to smearing and other shortcomings, improve the speed and accuracy of the dispensing.

The main objective of this article is the design of the equipment with three-axis simulator which is driven by the Brushless DC torque motor. In the paper, We also analyze the aspects that affect the character of the low speed performance of the simulator. Given the character of the torque interruption, we apply the compound control strategy to compensate the interruption in the position servo system. It was found that the simulation results proved that the application of the compound control for counteracting the interruption could improve the capability to counter the interruption outside the system, and it also enhance the characteristics of the low speed to become well from the study of the simulation of the system.
