Voltage Control of the Boost Converter: PI vs. Nonlinear Passivity-based Control
We carry-out a detailed analysis of direct voltage control of a Boost converter feeding a simple resistive load. First, we prove that using a classical PI control to stabilize a desired equilibrium leads to a very complicated dynamic behavior consisting of two equilibrium points, one of them always unstable for all PI gains and circuit parameter values. Interestingly, the second equilibrium point may be rendered stable -- but for all tuning gains leading to an extremely large value of the circu…

Jerry Falwell and #MeToo agree that men who want sex are evil.
When Christian Fundamentalist Conservatives and Radical Feminists agree, people who still have some common sense need to stick together and fight for sanity.

The Democrats Are Now The Moral Majority - in the worst possible way One of the most fascinating things in the last few decades of U.S. politics is the total reversal of the sex-positive vs sex-negative positions of the two main parties. In the 80s and 90s the Republicans were the party of Jerry Falwell and the Moral Majority. The sex-phobic Puritan idiots were all in the GOP. The sex-positive enjoy life and don't suppress healthy natural desires party was the Democrats. In the 90s the …

The Great Comets of 1843 and 1882 at Their Previous Return to Perihelion in the Twelfth Century: One Spectacular, the Other Dull
New insights into the history of C/1843 D1 and C/1882 R1, the two celebrated Kreutz sungrazers, are provided by assessing evidence on their appearance at the previous perihelion return, known as X/1106 C1 and the Chinese comet of 1138 (Ho's No. 403), respectively. The conditions differed vastly because of disparities in geocentric distance, solar elongation, and phase correction (forward scattering), all linked to the arrival times (early February vs early August). The conclusions include: the …
