A method based on adaptive sliding mode variable structure controller is presented for projective synchronization of a class of chaotic system with perturbations. We design a control law and a adaptation mechanism. With this controller controlled, the drive system and response system achieves projective synchronization and control even if exist perturbations and parameter mismatch. The controller is simple and easy to implement. Moreover, no restrictive assumption is imposed on the system. Thus, the range of applicability the proposed method becomes broad. Theoretical analysis and simulation results illustrate the validity.

In the general slidingmode control, often choose a hyperplane to make the system reach the slidingmode, the tracking error and gradual decay to zero, and the gradual convergence of the speed by selecting the sliding surface parameter matrix of arbitrary regulation, in spite of the state in any case tracking error will converge to zero in finite time, but also a certain degree of jitter. In order to obtain better performance, this paper presents a fuzz-based Terminal sliding mode variable structure control, that is, the introduction of non-linear function of sliding hyperplane constructed Terminal side, while Terminal by adding fuzzy control regulation,Lyapunov proof and the final adoption of MATLAB-MIMO system simulation, the control strategy obtained has better robustness, stability and good control effect.

The paper studies sliding mode variable structure control system for a novel gearless windlass balance oil pumping unit(GWBOPU) driven by low-speed and high-torque permanent magnet synchronous motor (PMSM). By analyzing the correlative relationships of the motor and the load, a mathematics model for GWBOPU is established. Base on this model, a speed slidingmode controller is designed by regarding the load speed as the control object. To guarantee the higher operating performance of the system, the running speed is also planned and designed according to different operating conditions. The simulation and experiment results show the control system has satisfied dynamic performance and strong robustness to disturbances.

By analyzing the correlative relationships of the motor and the load of a crane lifter, a mathematics model for a crane system is established. Based on this model, a speed slidingmode controller is designed by regarding the load speed as the control object. To guarantee the higher running performance of the system, a rotor flux slidingmode controller and a rotor flux observer are designed. The running speed is also planned and designed according to different operating conditions. A simulation model of the control system is presented in Matlab/Simulink environment. The simulation results show the control system has satisfied dynamic performance and strong robustness to disturbances.

To satisfy with the high-power control of the asynchronism motor control drive system, this paper devised a novel reaching law of sliding mode variable structure control strategy and analysed this control strategy for vector control system of asynchronism motor and the high-frequency chattering phenomenon in traditional slidingmode controllers. The simulation results demonstrate that the control strategy can ensure rapid dynamic speed response during the efficiency optimization at low loads and decrease chattering phenomenon effectively, greatly improve the robustness of asynchronism motor and improve control quality.

To achieve the coordination control of voltage and current compensation with excellent system robust, a unified power quality conditioner (UPQC) controller design procedures based on sliding mode variable structure control (SMVSC) is proposed. First, making use of high self-adaptability and strong robustness of SMVSC, linearization and decoupling control of dynamic model for UPQC could be achieved by proper nonlinear coordinate transformation and state feedback. Secondly, according to the difference between voltage and current compensation unit, different dynamic inversion management are adopted. And then, different slidingmode surfaces are select to design corresponding sliding controller. Finally, both simulation and prototype test results shows that the developed controller has excellent static and dynamic performance and the method proposed is effective and feasible.
