摘要：Self-validating (SEVA) pneumatic actuator is a new generation of actuator which can not only give the corresponding output according to the input control variable but also give the accuracy of the control output and status of the actuator itself and other information. A dual processor system is implemented using C8051F060 and TMS320F28335 to acquire the signals and complete fault detection, diagnosis and self-validating parameters calculating. C8051F060 is used to data acquisition and preprocessing of the actuator inner signals, and communicate with Host PC.TMS320F28335 is used to run the self-validation algorithm and fault diagnosis algorithm and transfer the self-validation outputs to C8051F060. Experimental results indicate that the sell-validating unit can acquire the actuator inner sensors data correctly in normal state and fault state. With software modification of DSP and MCU, the system can be used in data acquisition and signal processing for other actuators.
