Design and functional test of positional system with linear actuator

The paper considers a positional system with a linear actuator and modal control. The use of the software extensions of the MATLAB‘s Control System Toolbox enabled a synthesis of the factors of the modal regulator for different types of the characteristic polynomials of the closed-loop system. Dynamic characteristics of the obtained system with different factors of the modal controller were estimated in by means of a mathematical model of the studied actuator in the Simulink application. The resulting structure and method of synthesis of a control system with the linear solenoid actuator provide an aperiodic nature of transient process of the working gear travel. This enables small displacements of various objects at uncertain parameters of power circuits and loads with a fast response time and minimal static error.
