In this paper, performance comparison of evolutionary algorithms (EAs) such as modified particle swarm optimization (MPSO) and improved asynchronous particle swarm optimization (IAPSO) is considered. EAs simulations are carried with minimization of IAE and peak overshoot as objective using one type of stopping criteria, namely, maximum number of iterations.(More)
Trajectory tracking and stabilization of a nonlinear single stage inverted pendulum is a complicated control problem, as nonlinearity is present inherently and external factors affect the equilibrium position. Sliding mode control (SMC) is a robust control technique, most popular for nonlinear system's controlling. In this paper, a new model based robust(More)
