You can retain control - for example, by retaining a majority of the voting rights. However, this is rarely a satisfactory solution, as your successors are likely to resent your interference.
A more practical approach is to discuss your wishes with your successors, and agree what values you want to see retained. These can be enforced either through a shareholders' agreement, or by amending the company's articles of association.
Be wary of limiting the business's ability to react appropriately as circumstances change in the future.
