Compound Control of Electromagnetic Linear Actuator Based on Fuzzy Switching
Abstract: Due to the motion
control system of electromagnetic linear actuator (EMLA) is a nonlinear system with
poor controllability; single control strategy has been difficult to meet the
requirements of its control. A compound control strategy based on inverse
system control (ISC) and proportional-integral (PI) is designed in this paper.
Switching between two algorithms, which is based on the fuzzy rules, prevents
the control algorithm to jitter and jump. System model is built under
Matlab/Simulink to do simulation analysis. The designed controller is
integrated into the system simulation model and the system software of digital signal
processor (DSP) controller. Simulation and test results show that the compound
control strategy using fuzzy switching rules achieves the smooth transition of
two control algorithms, and the goal of any position location, and continuous
adjustment in 0~4mm lift. Positioning accuracy is up to ± 0.02mm, while the
response time is less than 10ms.
