Design and control of radome transmissivity measurement test system

In this thesis, the design and position and velocity control performances of a two-degree-of-freedom RTMTS are investigated. First, the system's conceptual and detailed designs were created. Then, the mass unbalances available in the azimuth and elevation axes, the equations of motion of the test system were calculated using Lagrangian equations. The RTMTS's main parts were identified, and the essential control algorithm for reliable control was created. The cross-coupling unit was developed using PMSM modeling and static mass unbalance. The general control system's model was generated in the MATLAB Simulink environment, and simulations were run. Different reference angular positions and velocities have been examined to see how well the system performs. PLC is used to control the real system, and the control model created in Simulink is embedded into PLC. The RTMTS has been demonstrated to arrive at the intended position at the desired time and with great accuracy in simulations and visuals of the real system. Various angles were used to measure the radome's transmissivity value, which was controlled in terms of position and speed. After that, the 3D radome surface was colored with the transmissivity values for each position, and the positions with low transmissivity were identified.
