“…Sliding Mode Controller (SMC) is a robust controller and it can perform exceptional tracking in presence of uncertainties and external disturbances. SMC is used extensively in many applications such as (a) Petrochemical systems for various processes control [1], (b) Servomotor position and speed control system [2], (c) Aerospace applications-the altitude control of spacecraft [3], (d) Automobile systems-the antilock braking control [4] (e) Robotics systems [5] (f) Mechanical systems [6]. The backstepping controller alone cannot provide the robustness to the uncertainty and disturbances to the present in the systems.…”

Magnetic Levitation System (MLS) is a nonlinear system and it is used extensively in many areas. The system's goal is to use the non-contact principle to magnetize the coil and cause the objects to float to a specific height. The magnetic force and the current flowing through the coil have a nonlinear relationship. In this paper first design of the backstepping controller is done to attain the wanted floating in presence of system related uncertainties and system behavior is witnessed. Then a Sliding Mode Controller (SMC) based on backstepping procedure is formulated. The control gains in this controller are designed in such a way that the characteristics polynomial whose coefficients are control gains is strictly Hurwitz and the closed loop system's asymptotic stability is assured. Simulations are performed and the magnetic ball tracking is observed considering step signal as reference in presence of disturbances. More accuracy is observed in terms of following the reference by the magnetic ball when it is used Sliding Mode Controller based on Backstepping technique instead of backstepping controller by considering pulse type disturbance. By simulation and analyzing results it is confirmed that the proposed control strategy is more effective.

“…Recently many researchers have been focused on the study of the variable-structure model-following control (VSMFC) system, which combines the model-following capability of the adaptive model-following control (AMFC) (Narendra and Annaswamy 1989, Chan et al 1990, Liaw et al 1992) and the fast response capability of the variable-structure control (VSC) (Ho and Sen 1990, Park and Kim 1991, Karunadasa and Renfrew 1991, Utkin 1993. The advantage in designing a model-following control system using VSC theory is that the transient response of model following can be prescribed in advance and is insensitive to parameter variations and external disturbance.…”

A toggle mechanism, which is driven by a permanent-magnet synchronous servo motor, with variable-structure model-following control (V SMFC) is proposed in this study. The rod and crank of the toggle mechanism are assumed to be rigid. The Hamilton principle and L agrange multiplier methods are applied to formulate the equation of motion. Based on the principles of the adaptive model-following control and the variable-structure control, a V SMFC system is developed to control the position of a slider of the toggle mechanism servo system. Numerical and experimental results show that the dynamic behaviour of the proposed controller-motor-mechanism system is robust to parametric variations and external disturbances.

“…However, the computation expenses and the requirement of expert knowledge for the system setup have seriously restricted their applications in practice. The sliding mode control is one of the effective methods to overcome the above problems [2][3][4][5][6]. It has many good features such as fast dynamic response, simplicity of design and implementation, and robustness to parameter variations or load disturbance.…”

This paper presents the speed control of the induction motor drive. The control strategy is based on the sliding mode technique. The decoupling between motor speed and rotor flux amplitude has been achieved using the field orientation principle. The control law has been designed such that the uncertainty due to motor parameters variation can be eliminated. Also, the chattering problem associated with classical sliding mode control has been solved by suggesting an adaptive load torque disturbance estimator. Digital simulations have been carried out in order to evaluate the effectiveness of the proposed scheme. The induction motor with the proposed controller has been tested through mismatched rotor resistance, and load torque disturbance. The results prove that the induction motor with the proposed controller has good robustness in face of uncertainties including load disturbance. Moreover, accurate tracking performance has been achieved.
