This paper shows how the significant developments available today can bring digital controls within the price range of all but the very simplest control systems and at the same time provide very significant flexibility not possible hitherto, except in the most complicated installations. New development in the form of the microprocessor chip has made it possible to design digital fuel controls at a cost equivalent to current analog systems. These developments free the control system designer from many of his previous limitations, but they also impose new constraints.

Surge Control

Under the Gas Machinery Research Council 2007 program, Southwest Research Institute has developed an application guideline to be used in the design and selection of centrifugal compressor surge control systems. The surge control system guideline provides a common reference on the required functionality of the surge control system components. The guideline benefits the user, system designer, and compressor manufacturer by enhancing the understanding of surge control system design to improve performance and reduce unnecessary cost. The guideline also provides methods of evaluating surge control system performance against recommended design criteria. This allows the operating company to determine if the surge control system will meet expectations. This paper highlights the critical issues of surge control system design based on the recommendations of the GMRC guideline. Due to the competing factors in the design of the compressor station, the optimal measurement instrumentation, piping layout and recycle valve are not always available. The surge control system designer must overcome these factors by designing against the limitations of the compressor station, the selected measurement instrumentation, and the various components of the control system.

Quadrotor is an unmanned aerial vehicle which is controlled by remote control. Unfortunately, not all of the remote control are easy to use, especially for people who have lacking abilities in piloting. This study aims to design a prototype system to control  quadrotor using hand movements, as an alternative to the conventional remote control that more simple. This system is consists of 2 parts, quadrotor and handheld. Both systems can communicate wirelessly using radio frequency 2.4 GHz. The handheld system will read the orientation angle of the hand by IMU sensor and it will be converted into a command to determine the direction motion of the quadrotor. To get the orientation angle from the IMU sensor data, we used DCM sensor fusion method. Quadrotor needs a control system that can make its respond runs optimally. In this study, the method of the control system that used is PID controller. The PID gain obtained using Ziegler-Nichols oscillation method and then fixed again by fine-tuned method.

The glycol regeneration process is an integrated part of the glycol dehydration unit (GDU) system. Each plant has a customized configuration to the needs of the process, for the case in this onshore field because the gas produced from the well is good enough with a fairly low water content, then does not use Glycol Contactor. Instead used low temperature separator and glycol generation unit. DCS DeltaV is used to operate, documentation and optimization of gas processes. By using oscillation method and closed loop system obtained PID tuning result with parameter P = 387, I = 57 and D = 53. The response of the control system is conditioned overshoot from its setpoint to accelerate the rise of the temperature plant. When the temperature of glycol regeneration is at 2620 F, the alarm will light Hi limit and Hi Hi limit at 2900 F, while at 2450F the alarm will light low limit and Low Low limit at temperature 00 F.
