The main aim for sliding control, or also called Variable Structure Control, is to control the nonlinear plant by introducing a sliding surface. The sliding surface should be reached by making the state of system approach this level. In this paper, an integral augmented sliding mode control (SMC+I) is proposed to improve the control performance of a plant with uncertainty giving the example of bench-top helicopter and the results are compared with the results obtained from conventional sliding mode control with and without a boundary layer. %K Sliding Mode Control %K Chattering Phenomenon %K Boundary Layer %K Pitch Angel of a 3-DOF Helicopter. %U http://ee.majlesi.info/index/index.php/ee/article/view/338
