Performance Analysis of Sliding Mode Control for Real-time Hybrid Test
نویسندگان
چکیده
The equivalent force control method uses feedback control to replace a mathematical iteration required to solve the nonlinear equation of real-time hybrid test with an implicit integration method. The commonly used PID controller as a candidate of equivalent force control has only limited robustness for nonlinear systems. For the nonlinear specimen in a real-time hybrid test, the sliding mode control is proposed to be used as the outer-loop controller of the equivalent force control. The design method of sliding mode control for equivalent force control is presented. The effects of key parameters of sliding mode controller on the performance of equivalent force control with are discussed and demonstrated through numerical simulation.
