“…Solenoid valves are being increasingly utilized, especially in the automotive industry, e.g., in electronic stability control systems [1], or in camless engines [2,3], and electromechanical switches can be widely found in drive-by-wire systems [4], household appliances [5], or battery chargers for electric vehicles [6], among others. In addition, novel designs of electric motors are still being investigated [7] and electromagnetic actuators are progressively replacing other types of linear-motion systems in vehicles [8] and in aeronautical applications [9] because of their accuracy, fast response, and efficiency.…”

Modeling the reluctance of an electromagnetic actuator is a critical step to analyze its dynamics and design model-based controllers. On the one hand, analytical expressions based on either theoretical or empirical models often lack accuracy due to model inconsistencies. On the other, numerical methods are much more precise but require exact information about the system geometry, materials and winding configuration. In this paper we present a new method that brings together the good properties of the finite element method and of system identification techniques to obtain an accurate description of the reluctance and its derivative. Since the method is designed to identify the unknown parameters of the system, it is particularly well suited for modeling existing commercial devices. An application on a safety valve used in gas lines is included to illustrate the method and a discussion on the results shows the advantages of our proposal.

“…In this context, reluctance machines present good environmental behavior due to their high efficiency and inherent ease of assembly and dismantling [2]. For these reasons, among others, there are several studies that have focused on new magnetic structures [3][4][5], in order to enhance their force performance [6] and increase force density by adding permanent magnets [7][8][9][10][11][12][13][14]. As an example, linear switched reluctance motors (LSRM) and linear permanent magnet synchronous motors (LPMSMs) have been proposed for propelling a ropeless elevator [15,16], for an automotive suspension system [17], and for a linear generator in direct drive wave-power converter [18].…”

Linear switched reluctance motors are a focus of study for many applications because of their simple and sturdy electromagnetic structure, despite their lower thrust force density when compared with linear permanent magnet synchronous motors. This study presents a novel linear switched reluctance structure enhanced by the use of permanent magnets. The proposed structure preserves the main advantages of the reluctance machines, that is, mechanical and thermal robustness, fault tolerant, and easy assembly in spite of the permanent magnets. The linear hybrid reluctance motor is analyzed by finite element analysis and the results are validated by experimental results. The main findings show a significant increase in the thrust force when compared with the former reluctance structure, with a low detent force.

“…The permanent magnets in the linear synchronous permanent magnetic machines (LSPMMs) bring an inevitable detent force. Articles [10,11] talk about thrust force output improvement and force ripple reductions for LSPMMs. In [10], the optimum design of a transverse LSPMM to reduce the detent force is presented by using a response surface methodology and genetic algorithms based on a finite element analysis and an experiment.…”

“…For elevator applications, an optimal structure design and magnetic force analysis that employs LSPMMs are presented in [7]. A multi-air gap LSPMM for aeronautical applications is designed and optimized for improved force output performance in [10]. Force ripple reduction can also be realized by characteristic linearization [12][13][14] and advanced force control methods [15][16][17][18].…”

Complimentary Force Allocation Control for a Dual-Mover Linear Switched Reluctance Machine

et al. 2017

View full text Add to dashboard Cite

This paper inspects the complementary force allocation control schemes for an integrated, dual-mover linear switched reluctance machine (LSRM). The performance of the total force is realized by the coordination of the two movers. First, the structure and characteristics of the LSRM are investigated. Then, a complimentary force allocation control scheme for the two movers is proposed. Next, three force allocation methods-constant proportion, constant proportion with a saturation interval and error compensation, and the variable proportion allocation strategies-are proposed and analyzed, respectively. Experimental results demonstrate that the complimentary force interaction between the two movers can effectively reduce the total amount of force ripples from each method. The results under the variable proportion method also show that dynamic error values falling into 0.044 mm and −0.04 mm under the unit ramp force reference can be achieved. With the sinusoidal force reference with an amplitude of 60 N and a frequency of 0.5 Hz, a dynamic force control precision of 0.062 N and 0.091 N can also be obtained.
