WebApr 10, 2024 · Conventionally, the range of and may be determined from the Routh–Hurwitz Stability Criterion, which is a pretty tedious task to compute elements in the Table for high-order systems ( ), and then solving the equations simultaneously. So far, there is no such function in the Control System Toolbox. Webpks = findpeaks (data) returns a vector with the local maxima (peaks) of the input signal vector, data. A local peak is a data sample that is either larger than its two neighboring …
