价格低廉的单片机和新型高速微处理器将全面代替模拟电子器件为主的DKJ电动执行器的控制单元，从而实现*数字化的控制系统。应用参数调度和模型辨识自适应控制将大大提高DKJ电动阀门执行器的控制性能。相对气动执行器、液动执行器来说，接线简单、功能强大、使用可靠的智能型电动执行器将不断扩大应用范围。传统的电动执行器一般被看作是线性系统，由放大环节和积分环节组成，但实际上，绝大多数电动执行器参数在运行期间会显著地发生改变。
Low-cost single-chip microcomputers and new high-speed microprocessors will completely replace the control unit of DKJ electric actuators, which are mainly analog electronics, and thus realize a completely digital control system. Application parameter scheduling and model identification adaptive control will greatly improve the control performance of DKJ electric valve actuators. Relative to pneumatic actuators and hydraulic actuators, intelligent electric actuators with simple wiring, powerful functions, and reliable use will continue to expand the application range. Traditional electric actuators are generally regarded as linear systems, which consist of amplification and integration. However, in reality, most electric actuator parameters change significantly during operation.
