冗餘校驗）(The CLRC663 is a highly integrated transceiver IC for contactless communication at
13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation
concept completely integrated for different kinds of contactless communication methods
and protocols at 13.56 MHz.
The CLRC663 transceiver ICs support the following operating modes
• read/write mode supporting ISO/IEC 14443A/MIFARE
• read/write mode supporting ISO/IEC 14443B
• read/write mode supporting JIS X 6319-4 (comparable with FeliCa 1 (see
Section 30.5) scheme)
• passive initiator mode according to ISO/IEC 18092
• read/write mode supporting ISO/IEC 15693
• read/write mode supporting ICODE EPC UID/ EPC OTP
• read/write mode supporting ISO/IEC 18000-3 Mode 3
The CLRC663’s internal transmitter is able to drive a reader/writer antenna designed to
communicate with ISO/IEC 14443A/MIFARE cards and transponders without additional
active circuitry. The receiver module )

PID
在PID控制中，微分信号的引入可改善系统的动态特性，但也易引起高频干扰。在误差扰动突变时尤其显出微分项的不足。若在控制算法中加入低通滤波器，则可使系统性能得到改善。(In PID control, the introduction of differential signal can improve the dynamic characteristics of the system, but it can also cause high-frequency interference. When error perturbations change abrupt, the deficiency of differential terms especially shows. If the low-pass filter is added to the control algorithm, the performance of the system can be improved.)
