In this paper, new sliding mode control scheme is presented for control of nonlinear processes. The method is proposed for process control applications in spite of model uncertainties, nonlinear dynamics and external disturbances. Using nominal system and related bounds of uncertainties, tuning parameters are obtained from reachability condition. The effectiveness of proposed method is shown by simulations...
This paper proposes a robust control strategy for industrial motion control using Extended State Observer (ESO). The proposed control enforces robustness without having the information of uncertainties and disturbances. The ESO is used to estimate the lumped uncertainties and guarantee robust performance. The robustness is analyzed for different uncertainties like backlash, friction and disturbances;...
This paper is concerned with design of second order sliding mode controller (SOSMC) with linear dynamic sliding surface. The sliding surface consists of a gain matrix having a variable damping ratio and settling time. The methodology explained is suggested to design systems with desired dynamic behaviour and robust for process uncertainties. In this study sliding mode control (SMC) and SOSMC are designed...
This study is motivated by the wide use of Proportional-Integral-Derivative (PID) controllers. In addition, the method of designing the PID controller can have a significant impact on its robustness. The potential of PID controller can be efficiently utilized only if it is tuned properly. We proposed a method of robust design of PID controllers for uncertain plant in the context of Quantitative Feedback...
In this work, formulation of a robust optimal guidance law for tactical missiles in end game scenario is proposed. Using the linearized missile target engagement model, an LQR based guidance law is designed to minimize the miss distance. Implementation of the guidance law, however, needs availability of system states as well as target acceleration. Since the latter represents an unmatched uncertainty,...
In this paper multiple surface sliding mode controller is designed for non-linear anti-lock braking system to control the wheel slip at a desired value. A second order actuator dynamics is considered in series with the anti-lock braking system. An inertial delay control technique is employed to estimate the lumped disturbances. The stability of overall system is proved. The performance of the proposed...
