Abstract. The article presents the rationale for improving the quality of transients during steering control of a tracked vehicle in order to increase its high speed performance. Based on the comparative analysis of the results of simulation modeling and experimental research of the controlled movement dynamics, it is established that high speed performance is restricted by transient overshoot of a vehicle response to the control input, by transient oscillation and insufficient oscillation damping. The solution of the problem of high speed performance increase is carried out by implementing a modern IT approach -by creating an automated system for stabilizing the vehicle motion trajectory -which applies Input Shaper for adjusting the control input. The research has established that, considering the control object under research, the best results are obtained by Zero Vibration Shaper -(ZV-Shaper), which enables to minimize limiting overshoot, and the transient becomes close to an aperiodic one. The quality of the control process is defined by natural frequency stability of the system, to which the Input Shaper in question is tuned. In this regard, it is appropriate to introduce monitoring and identifying natural frequency into the control system. This creates conditions for increasing vehicle high speed performance, including on soils with bad traction properties..One of the main operational properties of high-speed tracked vehicles is high speed performance represented by high-speed qualities. Increase in power-to-weight ratio in vehicles up to 25 kW, improvement of transmissions, of motion control systems and data information systems provide for increase in potential high-speed qualities of modern tracked vehicles. However, the manifestation of potential high-speed qualities is limited by a number of dynamic phenomena, which characterize controllability at rectilinear motion and during turning, especially at vehicle robotization.Severe vehicle operation conditions, limited possibilities for organizing maintenance service, insufficient reliability of electronic devices and hydrostatic drives, as well as cost limits for the steering control system lead to various suggestions on creating simple steering mechanisms and control systems. These systems have their own merits in terms of weight and volume indicators, simplicity, costs, a degree of design and technological perfection of the structural components. Steering devices with discrete properties, with which many pre-developed vehicles as well as the modern advanced TM-140 transport vehicle, intended for severe service conditions of the Arctic region, are equipped, can be referred to such control systems.Moving along the roads with the hard surface coating (asphalt, concrete, frozen soil), with bad traction properties and intensive change of curvature, the high speed characteristics of the vehicles equipped with the steering control system (SCS) with discrete properties are limited and do not exceed 36 … 38 km/h. It is explained by impossibility of variable (step...
