This paper presents the comprehensive numerical analysis of four, second order sliding manifold control algorithms to estimate rotor angle/position, θe, sensorlessly in brushless DC synchronous machine, namely, twisting, super twisting, convergence law and quasi-continuous sliding controller. The Lyapunov stability and convergence along with trajectories in the discrete time is also analyzed for each of these algorithms for both continuous and discontinuous controls.
