In this study, firstly, we compare various kinds of imitator robots and then by investigating of various fish robots properties, we design a mechanism and control circuit for a kind of these robots which its structure was inspired from knife fish. This robot has a segmental anal fin in its bottom which produces required force for advancement and maneuver. It consists of two servomotors and uses a kind of mechanical system to change direction and depth which is presented in this work. Another property of this robot is the existence of density control box for robot suspension which increases its capability for freight. The required signals are sent to this robot to produce the movement and maneuver by using a control handle and a wireless system which are installed on a control board. Therefore, it is possible to control the robot from out of the pool. In this paper, an electrical circuit is designed to control servomotors which enables us to control revolution, speed and phase differences of neighbor servomotors in fins. We also control two servomotors to regulate direction and depth.

Graphical Programming Language

This paper deals with an implementation method of component-based Petri nets system based on a graphical programming language (LabVIEW). LabVIEW is not only a graphical programming language, but also a virtual instrument platform which is widely used in virtual measurement and control system. The Places (token number) of Petri nets are represented by Numeric Controls of LabVIEW. The Transitions of Petri nets are represented by subVIs of LabVIEW. Transition subVI will change the tokens of Places by the Numeric Controls' Reference when it is fired. This method will make it ease to implement a Petri net by simply combining Place and Transition components (subVI). The example implementing a special Petri net shows that the Front Panel of the controller reflects the system operating state directly; the Block Diagram is similar to the topology of original Petri net. The combination of two graphic languages makes the modeling, analysis and formal verification of measurement and control system based on Petri nets easier.

Increasing in energy consumption, particularly with the ever-increasing growth and development of urban systems, has become a major concern in most countries. In this paper, the authors propose a cost-effective ZigBee-based building energy monitoring and control system (ZBEMCS), which is composed of a gateway, a base station, and sensors. Specifically, a new hardware platform for power sensor nodes is developed to perform both local/remote power parameter measurement and power on/off switching for electric appliances. The experimental results show that the ZBEMCS can easily monitor energy usage with a high level of accuracy. Two typical applications of ZBEMCS such as subentry metering and household metering of building energy are presented. The former includes lighting socket electricity, HVAC electricity, power electricity and special electricity. The latter includes household metering according to the campus’s main function zone and each college or department. Therefore, this system can be used for energy consumption monitoring, long-term energy conservation planning, and the development of automated energy conservation for building applications.

The problem of electricity losses management in distribution electric networks (DEN) operating in conditions of asymmetry of currents and voltages is reviewed. As it is known, the asymmetry factor leads to significant losses of active power and, as a result, decreases the efficiency and technical and economic indicators of the DEN. The purpose of the control is to minimize technical energy losses in the distribution network based on the creation of an automatic control system (ACS) for the process of balancing a three-phase network in the composition of automated meter reading and control system (AMRCS). The latter are currently being widely implemented to automate information processes in DEN. However, AMRCS does not include in its composition technologies designed to solve the problem under review. A method is proposed for constructing a digital ACS controller, the main function of which is to maintain phase currents at the network input at a given level in real time. The concept of the method is based on the idea of the desired redistribution of electricity flows between the phases of the distribution network by appropriate switching of single-phase consumers (customers) so that the minimum spread of phase currents from their specified level is ensured. To achieve the goal of control, criterion functions are constructed that determine the qualitative indicators of the functioning of the ACS. Algorithms for the functioning of the digital controller and the formation of control actions on the subject have been developed. The latter are a digital code containing data on the coordinates of electricity meters of consumers of a three-phase network to be switched to another phase.

The SkyTrakker™ is a highly accurate and highly efficient parabolic trough control system. The system includes the microprocessor control board, separate motor controller, and sensors (temperature, position, hydraulic pressure). The SkyTrakker™ has several distinct advantages and design features that provide better manufacturability, shorten installation time, and reduce O&M cost. Some of the advantages and features are: 1. Maximum control and performance with reduced parasitic power consumption. 2. Lower motor input power consumption during deploy, tracking and stow (the SkyTrakker™ uses 52% of the power consumed at NSO). 3. Simple 110v AC single-phase motor requirements with digital motor interface to reduce parasitic power consumption at motor start-up and during tracking. 4. Local or remote monitoring and control. 5. Separate motor control providing a high level of motor power isolation from the electronics. 6. Microprocessor based control board offering fast response, monitoring of HTF temperature, SCA position, hydraulic pressures, and control of the motor. 7. Enhanced field diagnostics to isolate position sensor and motor control problems and provide run-time status of operation. 8. Accurate tracking using virtual tracking algorithms, eliminating the use and maintenance of sun sensors. The SkyTrakker™ control system is modular and designed for quick assembly and installation at the SCA pylon. The major sub-system parts (control board and motor controller) are pre-assembled and are mounted on a pre-wired mounting panel. The NEMA 4 electrical enclosure can be mounted to the pylon with or without the internal pre-wired panel, providing installation flexibility when building the field. All control system components (control board, motor controller and sensors) can be easily replaced in the field. And motor life is greatly extended due to reduced overall power and reduced parasitic power consumption.

Operating Points

Pulp and paper processes frequently present nonlinear behavior, which means that process dynam-ics change with the operating points. These nonlinearities can challenge process control. PID controllers are the most popular controllers because they are simple and robust. However, a fixed set of PID tuning parameters is gen-erally not sufficient to optimize control of the process. Problems related to nonlinearities such as sluggish or oscilla-tory response can arise in different operating regions. Gain scheduling is a potential solution. In processes with mul-tiple control objectives, the control strategy must further evaluate loop interactions to decide on the pairing of manipulated and controlled variables that minimize the effect of such interactions and hence, optimize controller’s performance and stability. Using the CADSIM Plus™ commercial simulation software, we developed a Jacobian sim-ulation module that enables automatic bumps on the manipulated variables to calculate process gains at different operating points. These gains can be used in controller tuning. The module also enables the control system designer to evaluate loop interactions in a multivariable control system by calculating the Relative Gain Array (RGA) matrix, of which the Jacobian is an essential part.
