This paper presents sliding mode control (SMC) design for a class of nonlinear systems in which the sliding surface is designed to be linear with time varying slope(s). The sliding surface design is based on the frozen-time approach. The nonlinear system is frozen at each operation step resulting in linear time invariant (LTI) model and the sliding surface is designed for the LTI model. The surface slope is updated at each frozen step which gives, in general, a moving sliding surface. The control term, on the other hand, is designed so that the moving sliding surface is reached in a finite time. Therefore sliding mode is achieved and the nonlinear system is restricted to stay on the moving sliding surface. We demonstrate the design methodology developed in this study, on an inverted pendulum model. The simulation results show the success of the method.

Sliding mode control for non-linear systems with adaptive sliding surfaces
Durmaz, Burak; Özgören, Mustafa Kemal; SALAMCİ, METİN UYMAZ (2012-02-01)
This study covers the sliding mode control design with adaptive sliding surfaces for a class of affine non-linear systems, which can be described by (x) over dot = A(x)x + B(x)u + f(x) + d(x, t). The main streamline of the study is the sliding surface design for such systems. The sliding surfaces are designed to be moving with varying slopes and offsets. The varying sliding surface parameters are determined by solving the state-dependent Riccati equations online during the control process. Thus, the sliding...
Sliding mode control of linearly actuated nonlinear systems
Durmaz, Burak; Özgören, Mustafa Kemal; Department of Mechanical Engineering (2009)
This study covers the sliding mode control design for a class of nonlinear systems, where the control input affects the state of the system linearly as described by (d/dt)x=A(x)x+B(x)u+d(x). The main streamline of the study is the sliding surface design for the system. Since there is no systematic way of designing sliding surfaces for nonlinear systems, a moving sliding surface is designed such that its parameters are determined in an adaptive manner to cope with the nonlinearities of the system. This adapt...
Cartesian Grid Mapper: Transformation Media for Modeling Arbitrary Curved Boundaries With Cartesian Grids
ÖZGÜN, ÖZLEM; Kuzuoğlu, Mustafa (2014-01-01)
A transformation electromagnetics-based approach is presented to facilitate the use of fixed Cartesian grids for modeling arbitrarily shaped (convex or nonconvex) curved boundaries in finite methods. The basic idea is to design transformation media adapted to the Cartesian grid by using the duality between the material parameters of the media and the coordinate transformation that maps the points of the Cartesian grid to the points on the original curved boundary. Such a transformation medium is named Carte...
Sliding mode control with optimal sliding surfaces for missile autopilot design
Salamci, MU; Özgören, Mustafa Kemal; Banks, SP (2000-07-01)
A new method is introduced to design sliding mode control with optimally selected sliding surfaces for a class of nonlinear systems. The nonlinear systems are recursively approximated as linear time-varying systems, and corresponding time-varying sliding surfaces are designed for each approximated system so that a given optimization criterion is minimized. The control input, which is designed by using an approximated system, is then applied to the nonlinear system. The method is used to design an autopilot ...
Linear mixed model with Laplace distribution (LLMM)
Gökalp Yavuz, Fulya (2018-03-01)
Linear mixed modeling (LMM) is a comprehensive technique used for clustered, panel and longitudinal data. The main assumption of classical LMM is having normally distributed random effects and error terms. However, there are several situations for that we need to use heavier tails distributions than the (multivariate) normal to handle outliers and/or heavy tailness in data. In this study, we focus on LMM using the multivariate Laplace distribution which is known as the heavy tailed alternative to the normal...
