A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.Polyalphabetic substitution ciphers are useful because the are less easily broken by frequency analysis, however if an attacker knows for instance that the message has a period n, then he simply can individually frequency analyze each cipher alphabet. The number of letters encrypted before a polyalphabetic substitution cipher returns to its first cipher alphabet is called its period. The larger the period, the stronger the cipher. Of course, this method of encryption is certainly not secure by any definition and should not be applied to any real-life scenarios.

用稳定边界法整定公式来求P,PI,PID的个参数，其中G是已知被校正系统的开环传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量Gc为校正器传递函数，p为系统开环极点的个数（不计重根个数，即多重根只计一个根）(With the Stable Boundary tuning formula seeking P, PI, PID' s parameters, of which G is known to be corrected and the system of open-loop transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters Gc for the corrector transfer function, p is the number of poles of open-loop system (excluding the number of multiple roots, that is a multiple root only to the root))
