Control system with improved robustness to disturbances

摘要

PURPOSE:To implement a motor control of a high performance by the memory members of a small number (1/Q), by striking a control signal for every detection signal and by updating a memory value for every Q-many detection signals. CONSTITUTION:A compensatory means 4 outputs a control signal c in accordance with a detection signal b from a speed detector 2. With a computing element 5 of the compensatory means 4 rotating errors and memory output values from a memory storage 6 are operated and memory values are substantially updated and stored in sequence, while memory output values and rotating errors are sequence, while memory output values and rotating errors are operated and synthesized to strike a control signal. Every time when a speed detection signal is obtained, a new control signal is struck. Every time Q-many detection signals are obtained, a memory value is substantially updated.
