摘要
具有自适应鲁棒PID控制器的设计,把系统辨识技术引入PID的设计,参数辨识采用序列二次规划(SQP)算法。对于结构确定,参数变化的系统,可通过自适应中的参数辨识环节对系统参数进行在线辨识,由辨识的结果,利用鲁棒PID控制器的设计方法进行PID参数整定,整定的参数应用于PID控制器;当系统模型参数变化超过一定范围时,辨识环节重新对系统进行辨识,再进行参数整定。
Self-adaptive robust PID controller design brings in the technology of system identification. The parameters identification is based on the SQP method. A system with structure fixed and variable parameters identifies the system parameters by the department of identification. And with the result of identification, the PID parameters tuning resorts to robust PID controller design, then the tuning parameters are used for PID controller. When parameters changing are out of a certain region, the system identification works again, then do parameters tuning again.
