Sliding Mode Control of VTOL System

Abstract

QUANSER QNET 2.0 Vertical Take Off and Landing (VTOL) system is a hardware device setup developed by National Instruments to study flight dynamics and vertical take-off and landing control. It has a DC Motor fan and adjustable counter weight. This is used exclusively for NI-ELVIS platform and LabVIEW software. The LabVIEW software is used to identify the model of the system by the method of best fit. The obtained second order model is tested for the open loop response using MATLAB SIMULINK. The various control methods like Proporional+Integral+Velocity (PIV) and Sliding Mode Control (SMC) are used to find the response of the system. It is found that the sliding mode controller provides better results compared to the PIV controller. Along with this, the actuator control is done using PI controller and it's response along with the system is analyzed and compared for both PIV and Sliding Mode Controller.
