Regarding the first issue, several methods of fixing the switching frequency, which include the incorporation of constant timing functions or circuitries into the of Switching Power 35, 52], the use of strategies as discussed in Chapter 5, and the indirect implementation of the SM controllers using the PWM approach as extensively elaborated in Chapters 6 to 10, have been proposed. As for the second issue, it has been widely known that the steady-state error of an SM-controlled system can be effectively suppressed through the use of an additional integral term of the state variables in the SM controller [11, 23, 52, 55, 63, 84]. This method is known as integral sliding mode control. When incorporated, the consequence is an SM-controlled system 1) with motion equation of the same order as the original system; and 2) with improved robustness and regulation property than the traditional SM-controlled system [102]. |
