In this paper we focus on the problem of the vertical movement control and approach to control algorithm implementation for unmanned aerial vehicle (UAV), known as a quadrotor. The most important control subsystems for the VTOL (Vertical Take-Off and Landing) are the attitude stabilization and the altitude regulation. Both systems are presented in this paper. However, the vertical movement of the platform has been confined to precise operations such as taking-off and landing. These actions demand high reliability and they are very crucial for autonomous flights. The design, analysis and the validation tests have been undertaken on the experimental aerial platform.
