Abstract
The increase in the independence of motor-vehicle engines from the influence of external loading on the engine shaft due to the improvement of the dynamic parameters of the elements of the automatic control system of angular speed is investigated. Research of dynamic parameters of the diesel engine is carried out by simulation . An invariant (combined) simulation model of the automatic control system of the diesel engine was developed and investigated and an automated control system of a self-propelled earthmover with the use of modern hardware was developed. The investigation of the invariant ACS of engine angular speed, which provides the optimum regardless of external disturbances <span style="text-decoration: line-through;">,</span> was continued by including the compensating element in the automatic control system. The recovery time of the steady-state value of engine angular speed under load is reduced by about 7 times, and the magnitude of angular speed drop is approximately 6 times. An algorithmic block diagram of the combined invariant ACS of engine angular speed is developed taking into account the influence of the compensating device for the case when the disturbing action is exponential and which takes into account the operation of the device of limiting the maximum permissible value of disturbance
