“…The dead zone happened when the maximum inductance occurred with no contribution on the generation of propulsion force. The dead zone will be larger with the increase on the absolute difference between the stator and translator pole width [30]. Table 2, it is found that the average thrust force will increase as stator pole width increase until a significant value of 19mm where there is reduction in the average thrust force.…”

“…However, increase in the number of turns leads to an increase of the slot area and magnetic core volume which will reduce the efficiency for the desired application. According to the study of Teixeira et al [30], three winding turn with 120, 226 and 264 turns are compared. The highest value of winding turns with 264 turns was found to have the highest thrust force with 970N compare to 226 turns with 705N; and 150 turns with 320N.…”

This paper presents the review of design variables optimization and control strategies of a Linear Switched Reluctance Actuator (LSRA). The introduction of various type of linear electromagnetic actuators (LEA) are compared and the advantages of LSRA over other LEA are discussed together with the type of actuator configurations and topologies. The SRA provides an overall efficiency similar to induction actuator of the similar rating, subsequently the friction and windage losses are comparable but force density is better. LSRA has the advantage of low cost, simple construction and high reliability compare to the actuator with permanent magnet. However, LSRA also has some obvious defects which will influence the performance of the actuator such as ripples and acoustic noise which are caused by the highly nonlinear characteristics of the actuator. By researching the design variables of the actuator, the influences of those design variables are introduced and the detail comparisons are analyzed in this paper. In addition, this paper also reviews on the control strategies in order to overcome the weaknesses of LSRA. Keyword:Actuator INTRODUCTIONLinear electromagnetic actuators (LEA) is a mechanism that generate linear motion due to the interactions of the magnetic fields and electromagnetic thrust. The major advantage of electromagnetic actuators over the conventional actuators is that it is almost maintenance free which is due to the absence of mechanical part such as gears The typical design of LEA can be characterized as three topologies: (i) Planar Single Sided; (ii) Planar Double Sided; (iii) Tubular. By comparison, the tubular topology of LEA has greater force density compare to planer topology actuator due to lesser flux leakage and tubular topology actuator minimized the stray magnetic field in the direction of travel along the stator and mover part [5]. Hence, the thrust force and

The development of smart city operation room of Makassar possesses several equally important stages which are equally important. There are four stages of development that are 1) data center construction, 2) camera distribution around the city , 3) wall room monitoring construction, and 4) smart operation room architecture construction. Since the time and cost are limited, it forces the project manager to be able to manage and control the priority in conducting the project. There are several usable criteria to determine the priority in conducting the project development through criteria consideration of the entire project stages. Project priority optimization system aims at making every single project activity effective including its evaluation process. It also exposes a ranking illustration of foremost project priority by providing cost preference of the entire development stages. Fuzzy Multi-Criteria Decision-Making is used to illustrate the project priority rank and further to determine the alternative optimal option in conducting the project. This enforces particular project to allocate its cost to the project with a higher level of cost necessity. The company, therefore, enables to make effective funding for the entire project based on the level of importance and time achievement and subsequently it promotes accessible technology integration. The conducted experiment suggests that the first construction of the project is data center construction followed by wall room construction and CCTV distribution. This is relevant with optimization value result of data center 0,405 higher than A2 0,42 for wall room construction and A3 CCTV distribution 0,24.
