Abstract

This study examines the dynamic characteristics and improvement of control methods for impulse hydraulic shock mechanisms used in high-performance hydraulic systems. The work focuses on eliminating the common discrepancy between theoretical and actual output parameters caused by inefficient processing of control signals. A mathematical model has been developed that describes the displacement, velocity, and acceleration of the actuator, taking into account nonlinear fluid dynamics and changes in external load. Based on this model, improved control methods are proposed, aimed at increasing system stability, reducing response errors, and improving the energy efficiency of the impact action. Numerical simulation has shown that adaptive input signal shaping significantly improves the system’s performance. Under identical modeling conditions, the proposed logic-based control method reduced the normalized force deviation by approximately 15–20% compared with the conventional control scheme. A logical structure for generating the input signal X(t) has been developed, ensuring more precise synchronization of dynamic processes. The results obtained contribute to the development of control methods for hydraulic shock mechanisms and propose improved algorithms applicable in engineering systems where high accuracy and reliability are required. Future plans include experimental verification of the proposed solutions on physical prototypes, as well as refinement of the mathematical models to account for the compressibility of the working fluid and real-time load changes.
