In this paper, a method is introduced which reduces the harmonicdistortion of the inverter output current, connecting the fuelcell to the AC load. Using FUZZY LOGIC-PI (FLPI), the controllingmethod is engaged in optimum tuning of the PI controllercoefficients of this converter. This converter has only one DC-ACboost inverter and simultaneously has the task of increasingvoltage level and generat...

The pole placement (PP) technique for design of a linear state feedback control system requires specification of all the closed-loop pole locations even though only a few poles dominate the system’s transient response characteristics. The linear quadratic regulator (LQR) method, on the other hand, optimizes the system transient response and does not directly impose the location of the dominant ...

This paper describes a low-jitter phase-locked loop (PLL) implemented in a 0.18m CMOS process. A sample–reset loop filter architecture is used that averages the oscillator proportional control current which provides the feedforward zero over an entire update period and hence leads to a ripple-free control signal. The ripple-free control current eliminates the need for an additional filtering po...

In a network which does not differentiate among users, the equilibrium rate for any user is primarily decided by the congestion control being used. By changing their congestion control schemes, “uncooperative” users can gain more than their fair share of bandwidth, at the cost of cooperative users. We present a control-theoretic algorithm to counteract uncooperative users by adjusting the price...

This paper shows how to use Markov Decision Processes to guide the actions of the operation personnel during a transient in a heat recovery steam generator (HRSG). The critical events shown correspond to situations where a strong participation of human operators is required. The aim is to help the steam generation control system to set the plant on a safe operation state. The proposed system al...

A control system combining input shaping and feedback is applied to a double-pendulum bridge crane subjected to external disturbances. The external disturbances represent naturally occurring forces, such as gusting winds. The proposed control method achieves fast point-to-point response similar to open-loop input-shaping control. It also minimizes transient deflections and disturbance-induced r...

This paper introduces a control strategy to simultaneously achieve asymptotic stabilization and transient frequency regulation of power networks. The command is generated by iteratively solving an open-loop cost minimization problem with stability constraints. To deal the non-convexity constraint, we propose convexification that uses reference trajectory based on system’s current state. We also...

Abstract The Baiyun gold deposits in the Qingchengzi ore concentration area have significant deep exploration potential. Transient electromagnetic (TEM) is conducted to identify ore-bearing strata and ore-controlling structures mining area’s periphery. Previous tests revealed that it challenging penetrate conductive layer obtain information using a conventional in-loop TEM method with an induct...

In order to solve the problem of low speed and stable course tracking small unmanned surface vessel (USV), lateral thruster are added driving structure USV, a backstepping control method is designed. By introducing Lyapunov function, error can converge region near desired meet transient steady performance system at same time. The adaptive applied thrust closed-loop remains for finite direct use...
