This study presents a new control system for a linear switched reluctance motor (LSRM). Type‐2 Takati‐Sugeno fuzzy system is used for the motor approximation. The uncertain parameters of the motor are described by the lower and upper membership functions. By constructing an integral sliding mode surface, an adaptive sliding mode controller is designed and dynamic stability of the sliding motion is verified using the Lyapunov function. The design of the proposed sliding mode surface is independent of the number of fuzzy rules and thus, computational complexity is significantly decreased. The control system is implemented on a double‐sided four‐phase LSRM and its performance is demonstrated by means of modelling and experimental results.
