dSPACE DS1104 Based Real Time Implementation of Sliding Mode Control of Induction Motor

“…Variable structure control (VSC) with sliding mode, or sliding-mode control (SMC), is one of the effective nonlinear robust control approaches, because it provides system dynamics with an invariance property to uncertainties once the system dynamics are controlled in the sliding mode [11], [12], [15], [16], [17], [18], [19], 20]. The first step of SMC design is to select a sliding surface that models the desired closedloop performance in state variable space.…”

“…The insensitivity of the controlled system to uncertainties exists in the sliding mode, but not during the reaching phase. Thus, the system dynamic in the reaching phase is still influenced by uncertainties [13], [14], [15], [16], [17].…”

“…, where u(t) is the input to the system and we assume that b>0 . A possible choice of the structure of a sliding mode controller is [15][16][17]:…”

“…Where eq u is called equivalent control which dictates the motion of the state trajectory along the sliding surface [15], [16]; k is a constant, representing the maximum controller output required to overcome parameter uncertainties and disturbances; s is called the switching function because the control action switches its sign on the two sides of the switching surface 0  s . For a second order system s is defined as [16], [17]:…”

“…But it also works as a general framework for real-time big data analysis [3] [4]. There are some techniques where data diffuse automatically propagate information from one channel to another [21].…”
