In this paper, a new method for the design of infinite impulse response fractional order digital integrator is proposed. The maximum phase deviation from a desired linear phase is minimized under the stability and relative magnitude response error constraints. The resultant design problem is nonconvex. An iterative convex optimization algorithm based on Gauss-Newton strategy is developed by converting the nonconvex constrained optimization design problem into a series of convex optimization subproblems. To approximate the desired frequency response, a pole factor is preassigned. design examples show that the iiR fractional order digital integrators have smaller maximum phase error and maximum relative magnitude response error than the competing.

This paper introduces a new approach for the design of iiR fractional-order digital differentiators exhibiting near-linear phase characteristics. The methodology focuses on minimizing the maximum phase deviation from an ideal linear phase under stability-triangle and relative magnitude response error constraints. The formulated design problem is inherently nonconvex. To address this, an iterative convex optimization algorithm is proposed, leveraging a Gauss-Newton strategy to transform the nonconvex problem into a sequence of convex subproblems. Empirical design examples demonstrate that the proposed differentiators achieve superior performance in terms of both maximum phase error and maximum relative magnitude error compared to existing counterparts in the literature.
