【 摘 要 】

This paper studies the effect of the choice of the test signal on the result of optimization of the regulator by the example of PID and PI2D structures. It is shown that if the quality response to ramp signals is necessary, optimization of the system only by the simple signals is ineffective. In this case, the resulting system is characterized by excessively large overshoot when the step is supplied to the system input. The paper proposes a method for designing an effective system consisting in numerical optimization for two parallel operating control systems. Its effectiveness has been proved by simulation.
