Even for this simple application, both approaches implement an EKF due to the nonlinearity imposed by the scale factor error In the approach of Section 71 the nonlinearity is induced by the accelerometer scale factor compensation in the time update In the approach of Section 74 the nonlinearity appears in the accelerometer portion of the measurement update In more realistic applications, the kinematics typically involve nonlinearities, so an EKF will be required in either approach In the approach of Section 71, there are no free tuning parameters All the parameter values are determined from the characteristics of the instruments Based on the results of observability, covariance, or simulation analysis, the designer may choose to combine or remove states or to tune the parameters determined from the sensor characteristics; however, there is a rigorous basis for the initial settings and subsequent tuning The basic design model is a Markov process driven by stationary white noise processes and therefore satis es the derivation assumptions for the Kalman lter The approach of Section 74 starts with a model hypothesis for the acceleration state In most applications, there is no time invariant Markov model for this state because the signal characteristics are determined by the end user and usually cannot be reliably predicted during the system design phase The design does involve free tuning parameters and does not satisfy the basic modeling assumptions of the Kalman lter Because both approaches implement EKF s the P matrix is not, strictly speaking, the error covariance matrix in either case However, as long as x is kept small, in the approach of Section 71 the linearization error is small, and P is typically a reasonable representation of the accuracy of x In the case of the approach of Section 74 the matrix P cannot be expected to be a reasonable characterization of the accuracy of x unless the assumed model for the acceleration turns out to be accurate Similarly, the EKF measurement update in Section 71 is the optimal linear correction The EKF measurement update in Section 74 is only optimal if the assumed model for the acceleration turns out to be accurate The computational load of aided navigation systems is typically dominated by the time update of the P matrix For the two algorithms, the computational load for the P matrix time and measurement propagation over each second of operation are compared in the Table 72 Eqn (721).

Rectifier diodes are available in various sizes, intended for different purposes Most rectifier diodes are made of silicon and are therefore known as silicon rectifiers A few are fabricated from selenium, and are called selenium rectifiers Two important features of a power-supply diode are the average forwvard current (Io) rating and the peak inverse voltage (PIV) rating There are other specifications that engineers need to know when designing a specialized power supply, but in this course, you only need to be concerned about Io and PIV

Electric current produces heat If the current through a diode is too great, the heat will destroy the P-N junction Generally speaking, when designing a power supply, it s wise to use diodes with an Io rating of at least 15 times the expected average dc forward current If this current is 40 A, the rectifier diodes should be rated at Io = 60 A or more Of course, it would be wasteful of money to use a 100-A diode in a circuit where the average forward current is 40 A While it would work, it would be a bit like shooting a sparrow with a cannon Note that Io flows through the diodes The current drawn by the load is often quite different from this Also, note that Io is an average figure The instantaneous forward current is another thing, and can be 15 or even 20 times Io, depending on the nature of the power-supply filtering circuitry Some diodes have heatsinks to help carry heat away from the P-N junction A selenium diode can be recognized by the appearance of its heatsink (Fig 21-2)

386 Power supplies Diodes can be connected in parallel to increase the current rating When this is done, small-value resistors are placed in series with each diode in the set to equalize the current burden among the diodes (Fig 21-3) Each resistor should have a voltage drop of about 1 V

The PIV rating of a diode is the instantaneous inverse, or reverse-bias, voltage that it can withstand without avalanche taking place A good power supply has diodes whose PIV ratings are significantly greater than the peak voltage of the ac at the input If the PIV rating is not great enough, the diode or diodes in a supply will conduct for part of the reverse cycle This will degrade the efficiency of the supply; the reverse current will buck the forward current It would be like having a team of rowers in a long boat, with one or two rowers trying to propel the boat backwards instead of forwards Diodes can be connected in series to get a higher PIV capacity than a single diode alone This scheme is sometimes seen in high-voltage supplies, such as those needed for tube-type ham radio power amplifiers High-value resistors, of about 500 for each peak-inverse volt, are placed across each diode in the set to distribute the reverse bias equally among the diodes (Fig 21-4) Also, each diode is shunted by a capacitor of 0005 F or 01 F
