In this paper, the overvoltage on a transformer terminated at a transmission line through a cable is considered. Also, the effects of the length and size of the cable on the amplitude of overvoltage and its harmonics are investigated. Simulations are performed using EMTP and their results show the longer cable the less amplitude of overvoltage on the terminal of the transformer.

A sliding mode controller is employed to improve the robust performance of the position control of an induction motor in response to mechanical parameter uncertainty or load torque variations. In this paper a discrete-time sliding mode controller is proposed for an indirect-vector controlled induction motor. Using the proposed controller, the position control of an induction motor is designed and the effects of the parameter uncertainty and the load torque variations on the performance of the controller are investigated. Simulation results reveal the effectiveness of the proposed controller.

A behavior-based control and learning architecture is proposed, where reinforcement learning is applied to learn proper associations between stimulus and response by using two types of memory called as short Term Memory and Long Term Memory. In particular, to cope with delayed-reward problem, a knowledge-propagation (KP) method is proposed, where well-designed or well-trained S-R(stimulus-response) associations for low-level sensors are utilized to learn new S-R associations for high-level sensors, in case that those S-R associations require same objective such as obstacle avoidance. To show the validity of our proposed KP method, comparative experiments are performed for the cases that:(1) only a delayed reward is used, (2) some of S-R pairs are preprogrammed, (3) immediate reward is possible, and (4) our KP method is applied.

In this paper we give a sufficient condition (in terms of an LMI) for the well-posedness of a feedback interconnection between a linear system and an incrementally sector bounded static nonlinearity. In particular, we prove the global invertibility of the algebraic constraint arising from the feedback interconnection and prove a suitable Lipschitz bound for the arising global inverse function. We also comment on the useful ramifications of the proposed condition on LMI- based anti-windup synthesis methods recently proposed in the literature, wherein possible numerical problems arising from solutions which are "almost" non well-posed are ruled out by enforcing a suitable Lipschitz constant on the inverse function.

In this paper a model based nonlinear controller for a Gas Metal Arc Welding (GMAW) system is designed. The controller uses nonlinear state feedback to exactly linearize and decouple the GMAW system. The linearized system is then controlled using model reference sliding mode controllers. The effect of parameter uncertainty over the closed loop system performance is investigated and simulation results show the effectiveness of the proposed controller.
