1. Introduction

The high-precision quick-response linear motion is often required in modern testing systems. If the linear motion is realized using the rotary motors with a mechanical transmission, the mechanical transmission will introduce the backlash and large friction. A voice coil motor (VCM) for automated manufacturing processes is a direct drive motor that uses a permanent magnetic field and coil winding to produce a force proportional to the current applied to the coil winding [1,2]. The fixed part is permanent magnet field and the moving part is coil winding. Because of the characteristics of small size and high-response speed, VCM has been widely used in high-frequency response DDV drives or auto-focus modules of digital cameras [3]. Recently, several control methods for VCMs have been proposed [4–9]. Oboe et al. proposed a PI control with its simple design [1]. Since the control gains of PI control are fixed, the control performance is influenced by the system uncertainties, friction, and load changes of movable parts. Yu et al. proposed an adaptive fuzzy logic PID control to achieve a short response time with fuzzy tuning the control gains [4]. The fuzzy rules should be pre-constructed to achieve the design performance by trial-and-error; however,this trial-and-error tuning procedure is time-consuming. A fuzzy sliding-mode controller was designed to achieve favorable position control performance [5]; however, it has difficulty in determining suitable membership functions and fuzzy rules. Wu et al. proposed a sliding-mode control system with a state-space observer to improve the control accuracy and robustness [6]; however, the control signal results in the chattering phenomena. Recently, several neural-network-based intelligent control systems had been proposed for VCM control [7–9]. The developed adaptive tuning law only considers the on-line parameter learning of neural networks but doesn’t consider the structure adjustment of neural networks. It implies that tracking accuracy would be not satisfied if inadequate hidden nodes of neural network, i.e. too many or too few, are predefined. Whether a control system is robust against system uncertainties is an important issue for controller performance assessment. It is known that sliding mode control (SMC) system is an effective control approach due to its excellent advantage of strong robustness against model uncertainties, parameter variations and external disturbances [10,11]. However, the chattering problem is one of the most critical handicaps for applying the SMC system to real applications. On the other hand, based on the fuzzy rules base of fuzzy controller having skew-symmetric property, a fuzzy sliding-mode controller (FSMC) system is proposed to offer a significant reduction in rule inferences and simplify the tuning of control parameter [12–14]. Since only one variable (sliding surface) is defined as the input variable for fuzzy rules, the number of the fuzzy rules for FSMC is smaller than thatfor fuzzy control which uses the error and change of error as the input variables. However, obtaining appropriate membership functions and fuzzy rules for the design of FSMC system remains a challenge.
