The DC series motor is widely used in heavy duty applications. The state estimation problem of this nonlinear system poses difficulties owing to the complex mathematical structure and turn out to be more challenging when the system is involved noisy state variables. A suitable nonlinear transformation matrix has been used for modelling the system in generalized canonical form, not necessarily control affine, to ensure it as uniformly observable system. A constant gain based Extended Kalman Filter (hereinafter EKF) has been used for achieving robust performance without compromising the benefits of original optimal Kalman Filter based gain design.

This paper proposes a monolithic capacitor current mode adaptive on-time (CCAOT) controlled buck converter. A capacitor current-controlled modulation scheme ensures an ultra-fast load transient response. However, this scheme suffers from sensing circuit mismatch-induced instability, hence a concise passive ramp is proposed to mitigate the problem. The small signal model of the scheme is established to demonstrate the design standard of the system parameters. Moreover, a V2-loop eliminates the circuit delay caused on-time pulse error and achieves a pseudo constant frequency. Implemented in a 0.18μm CMOS process with a 4-MHz high switching frequency, this circuit occupies a total area of 1189 μm by 1199 μm in width and length including the pad ring. Finally, the experiment results show a fast load transient response, which is 42mV voltage drop and 1μs response time under the conditions of 1.1V output voltage and 1A load step-up with 1A/500ns slew rate. In addition, the frequency variation is 2%for a 1A load step and there is no instability issue in this work. IEEE
