In the work, dynamics of a controlled anti-aircraft missile launcher mo-unted on a moveable base (wheeled vehicle) is analysed. Pre-programmed Controls were used for basie motion of the launcher during target inter-ception, and stabilizing Controls were applied to counteract disturbances resulting from the operation of the anti-aircraft system. This type of con-trol allows setting the longitudinal axis of the missile with respect to the target linę of sight irrespective of the carrier vehicle motion. The system vibrations are due to road-induced excitations and they act directly on the vehicle, the missile launch and the control of launcher basie motion. Selected results of Computer simulation were presented graphically.

Key words: dynamics, control, launcher, missile

1. Introduction

Modern self-propelled anti-aircraft missile systems with short-range self-guided missiles should be able to detect, identify and track aerial targets when the launcher-carrier vehicles are in motion. To improve the system accuracy, it is necessary to apply pre-programmed Controls for target detection and cor-rective Controls for target tracking (Dziopa, 2004, 2005, 2006a; Koruba, 2001; Koruba and Osiecki, 1999).

Synthesis of the launcher control involves determination the impact that road-induced kinematic excitations may have on the launcher performance. It is desirable that any transitional process accompanying terrain unevenness (a bump) be optimally attenuated.

In this paper, motion of a launcher-missile system was considered in a three-dimensional Euclidean space and Earth’s gravitational field. There were
