This paper is focused on design of a new active control engine mount (ACM), which is both compact in size and cost effective. The ACM, consisting of an electrodynamic actuator as the active element, flat springs and a sliding ball joint, is different in structure from the previous ACM designs based on the conventional hydraulic engine mount. Dynamic characteristics of the proposed ACM are extensively investigated before a prototype ACM, which meets the design specifications, is built in the laboratory. For cost effectiveness, a feed-forward control algorithm without a feedback sensor is used for reduction of the transmitted force through the ACM by the engine. The prototype ACM is then harmonic-tested with a rubber testing machine for verification of its control performance as well as adequacy of modeling. Experimental results show that the proposed ACM is capable of reducing the transmitted force by 20 dB up to the frequency range of 60 Hz.

This paper presents the performance evaluation of control techniques for the reduction of capacitors in drivers for actuation LED.Through the active control of the driver output current, the ripple from the PFC stage of the current can be controlled, keeping itat levels appropriate to the technical standards, being IEC 61000-3-2 Class C and IEEE 1789. This control allows the outputvoltage ripple to vary at higher amplitude levels, allowing the use of a lower capacitance bus capacitor, therefore longer life usefuland reliability.The analyzed electronic system consists of the Buck-Boost converter was performed at the power control stagefor different bus voltages and output power. Different controller structures were analizes, in order to obtain an analysis of theinfluence of these controllers in the reduction of bus capacitance. Thus obtaining a greater ripple in the bus voltage, maintainingagreement with IEEE 1789 standard regarding current ripple limits on LEDs.
