In the reaching mode, the control dynamics depend on system parameters; but in the sliding mode they depend on the hyperplane, this is the invariance property of the sliding mode (Drazenovic 1969). This paper presents basic sliding mode control theory, so I will use the 2nd-ordered SISO canonical. More.
Out of many robust non-linear control strategies, a further development in sliding mode control (SMC) strategy is considered in this thesis because of its simplicity and robustness. There have been many contributions in the SMC field in the last decade. Many existingmethods are available for the SMC design for second-order systems. However, the.
The optimisation of Sliding Mode controllers for marine vehicle guidance is presented in this thesis. This study is concerned with two optimisation methods which are based on natural processes. The first is Simulated Annealing which involves processes analogous to those involved in the cooling process in metallurgy. The second involves Genetic Algorithms which are based on the evolutionary.
On discretization of sliding mode control systems Author(s) Wang, B: Year 2008 Abstract Sliding mode control (SMC) has been successfully applied to many practical control problems due to its attractive features such as invariance to matched uncertainties. The characteristic feature of a continuous-time SMC system is that sliding mode occurs on.
In consideration of these challenges, the main goal of this thesis is: To design a stability-guaranteed nonlinear flight control framework with reduced model dependency and enhanced robustness.

Smooth chattering free sliding mode control addresses the issue of chattering and provides smooth control action thereby re-moving the chattering from the sliding mode controller. The methods used for this pur-pose is the boundary layer control laws or by using the variable gain or adaptive sliding mode techniques. The resulting control action.
Sliding mode has been applied to current controller technology to boost converter. Fig 3 represents the basic circuit diagram of the boost converter controlled by the sliding mode controller. This control plan for boost converter starts with selecting the sliding surface. At present, the continuous growth results in direct surface almost zero.

The work here reported tackles the problem of controlling in sliding-mode a boost converter supplying a constant power load (CPL). A linear switching surface is proposed to overcome the intrinsic unstable behavior of the converter in both on and off states, this resulting in a significant mitigation of the inrush current and a high degree of output voltage regulation.
This thesis analyzes the effects of the motion in the boundary layer of some sliding surfaces in the performance of sliding mode controllers for power electronic converters. In converters with multiple inputs and multiple internal states a sliding mode controller stabilizing the system imposes sliding on a manifold residing in the intersection of multiple switching surfaces. Systems sliding in.
The thesis considers the development of robust output feedback sliding mode controllers for linear time invariant uncertain systems where output information alone is available to the controller. Two approaches to controller design are discussed. The first uses only the plant dynamics and is called static output feedback sliding mode control. It.
In this thesis, it is tried to have robust performance with reduced chat- tering. For this purpose, a novel output feedback based sliding mode strategy is proposed for uncertain nonlinear systems which is based on the existing the- ory of dynamic sliding mode and basic theory of integral sliding mode control. The proposed cont enhances the.
